path: root/fs/hfs/ChangeLog

1999-04-12  a sun  <asun@hecate.darksunrising.blah>

	* file_hdr.c (hdr_read): added rootinfo behaviour for DID header.

1999-04-11  a sun  <asun@hecate.darksunrising.blah>

	* super.c (parse_options): added s_version so that we can select
	between different versions of the same layout.

1999-04-05  a sun  <asun@hecate.darksunrising.blah>

	* linux/hfs_fs.h: unified netatalk and appledouble header format. 
	added in all of the AFP attribute bits.

	* file_hdr.c: added netatalk appledouble v2 compatible headers. 

1999-01-30  a sun  <asun@hecate.darksunrising.blah>

	* catalog.c (hfs_cat_move): fixed corruption problem with
	renames.

1999-01-27  a sun  <asun@hecate.darksunrising.blah>

	* file_hdr.c (get/set_dates): got rid of broken afpd times. NOTE:
	you must use netatalk-1.4b2+asun2.1.2 or newer for this.

1998-12-20  a sun  <asun@hecate.darksunrising.blah>

	* bdelete.c (del_root): assign bthLNode and bthFNode only if the
	root node becomes a leaf node. Disk First Aid no longer
	complains. Norton Utilities, of course, has decided that it
	doesn't like the root node number. bleah. i think that it might be
	due to Norton Utilities not expecting the root node to have moved.

1998-12-16  a sun  <asun@hecate.darksunrising.blah>

	* sysdep.c (hfs_revalidate_dentry): fix inode dates when there's a
	timezone change.

1998-12-15  root  <root@hecate.darksunrising.blah>

	* extent.c (new_extent): expand block size variables to handle
	u32. 

	* mdb.c (hfs_mdb_get): AlBlkSiz shouldn't be capped at 65535. we
	should be able to handle much larger volumes now.

1998-11-21  a sun  <asun@hecate.darksunrising.blah>

	* hfs_sysdep.h, hfs_fs.h: added hfs_from_utc/to_utc to deal with
	date differences on hfs formatted media. 

	NOTE: hfs extended keeps everything in utc, so we'll need to deal
	with that when appropriate.

1998-11-12  a sun  <asun@hecate.darksunrising.blah>

	* extent.c (shrink_fork): added some lock_bitmap/unlock_bitmap's
	to protect hfs_clear_vbm_bits. we should no longer have problems
	with free_ablocks wrapping around.

1998-11-02  a sun  <asun@hecate.darksunrising.blah>

	* mdb.c (hfs_mdb_get): plugged up an mdb failed initialization
	leak.

1998-10-31  a sun  <asun@hecate.darksunrising.blah>

	* version.c (hfs_version): bumped to version 0.96.

	* mdb.c (hfs_mdb_commit): you only write out the alternate MDB
	when the catalog or extents overflow files grow. that just leaves
	the btree corruption problems. bleah (whilst deleting a bunch of
	files, more of the btree can get pruned away than desired).

1998-10-30  a sun  <asun@hecate.darksunrising.blah>

	* dir.c: fixed a bunch of silliness with deletions. make sure to
	zero out stuff and set mark_inode_dirty().
	
1998-10-29  a sun  <asun@hecate.darksunrising.blah>

	* string.c (hfs_strcmp, hfs_streq, hfs_strhash): converted them to
	take name/len arguments instead of hfs_name to reduce copying.

	* dir.c, dir_nat.c, dir_cap.c, dir_dbl.c, sysdep.c: modified
	relevant areas to reflect string.c changes.
	
1998-10-28  a sun  <asun@hecate.darksunrising.blah>

	* hfs.h (hfs_lookup_dentry): oh my. more silliness. make sure to
	have the d_lookup use the same hash value as the one generated by
	hfs_hash_dentry. i also changed the argument order.
	(hfs_drop_special): change the argument order to be more in line
	with what the dcache stuff looks like.

	* sysdep.c (hfs_compare_dentry): the compare was returning the
	wrong value for correct matches and causing all sorts of
	mischief. this fixes both directory counts and mounting on top of
	hfs volumes.

	* file.c, file_cap.c, file_hdr.c: added mark_inode_dirty()'s in
	the relevant places.

1998-10-11  root  <asun@hecate.darksunrising.blah>

	* mdb.c (hfs_mdb_get): moved initialization of mdb->entry_dirty
	list to here to deal with trying to read a bad hfs volume.

1998-10-10  a sun  <asun@zoology.washington.edu>

	* inode.c, catalog.c, dir_*.c, sysdep.c: parts of the dcache
	conversion didn't get done properly. specifically, i forgot to
	move the hfs_cat_puts into the right place. that's fixed now.

1998-09-11  a sun  <asun@purgatorius.zoology.washington.edu>

	* mdb.c: altered mdb struct to reflect hfs plus usage.

1998-08-27  a sun  <asun@purgatorius.zoology.washington.edu>

	* file.c, file_hdr.c, file_cap.c: dealt with the remaining
	copy_to/from_user() error cases.

1998-08-26  a sun  <asun@purgatorius.zoology.washington.edu>

	* super.c (hfs_read_super): fixed to deal with cdroms. why doesn't
	the cdrom layer call the partition table code?

Wed Jan 21 14:04:26 1998  a sun  <asun@zoology.washington.edu>

	* inode.c, sysdep.c
	use d_iput to uncache dentry from catalog entry instead of relying
	on put_inode. no more NULL pointer dereferences!

	* catalog.c
	cleaned up hfs_cat_put a little.
	
	ISSUES (non-fatal): mv dir dir2 while creating files in dir screws
	                    up directory counts.
		
			    deletion using netatalk screws up directory
 			    counts.

Thu Jan 15 19:14:28 1998  a sun  <asun@zoology.washington.edu>

	* catalog.c
	make deletion happen when requested instead of waiting until
	an hfs_cat_put as the dcache can hold onto entries for quite
	some time.

Wed Jan 14 14:43:16 1998  a sun  <asun@zoology.washington.edu>
	
	* catalog.c
	the current catalog allocation scheme allocates
	PAGE_SIZE/sizeof(struct hfs_cat_entry) entries at a time and keeps
	a pool of free entries up to this allocation unit * 8.

	* inode.c
	make sure to always hfs_cat_put if hfs_iget is going to return
	NULL.

	* string.c, catalog.c
	use linux' hashing method to generate hashes. the old hashing was
 	getting collisions. catalog.c also has a larger hash table to
 	prevent collisions.
	
Tue Jan 13 13:06:01 1998  a sun  <asun@zoology.washington.edu>

	* version.c
	bumped to 0.95+asun3

	* catalog.c
	re-wrote to dynamically allocate/delete catalog entries. on a 486,
	entries fit into the size-256 slab.

Wed Jan  7 19:33:33 1998  a sun  <asun@zoology.washington.edu>

	* inode.c 
	don't hfs_cat_put gratuitously in hfs_iget. that's a bad
 	idea and results in screwed up entry counts.

Tue Jan  6 14:38:24 1998  a sun  <asun@zoology.washington.edu>

	* version.c
	changed it to 0.95+asun2

	* sysdep.c
	altered catalog entry pruning to make sure that an iput
	gets done. for some reason, shrink_dcache_parent wasn't
	doing it.

	* catalog.c
	added a global dirty list to check for pruning.
	
Tue Jan  6 12:29:52 1998  a sun  <asun@zoology.washington.edu>

	* catalog.c
	re-wrote it to be similar to 2.1.x inode.c. this should
 	at least make catalog.c SMP safe. 

	* hfs.h, linux/hfs_fs.h
	moved dentry operations into hfs.h. these probably should
	be moved somewhere else.

	* super.c, dir_cap.c, dir_nat.c, dir_dbl.c, sysdep.c
	added dentry ops to hash everything to lowercase.

Sun Dec 28 22:48:53 1997  a sun  <asun@zoology.washington.edu>

	* sysdep.c, catalog.c, hfs.h
	as a temporary workaround until catalog.c gets re-written, 
	i flush the dcache if we need more entries. 
	
Fri Dec 19 15:11:21 1997  a sun  <asun@zoology.washington.edu>

	* dir_dbl.c
	statically allocate tmp_name instead of doing it dynamically.

	NOTE: well, those pesky hfs_cat_put messages still aren't gone. in
	addition, catalog.c needs to be modified to free up some entries
	when the cache gets filled up. 

Sun Dec 14 11:51:11 1997  a sun  <asun@zoology.washington.edu>

	* linux/hfs_fs.h
	moved the dentry stuff into within the #ifdef __KERNEL__ 
	part of hfs_fs.h and cleaned up a little.

Sun Dec 14 11:24:54 1997  a sun  <asun@zoology.washington.edu>

	* dir.c
	changed hfs_rename to delete all old dentries. hfs_cat_put
	messages on umount should be a thing of the past now.

Sun Dec 14 01:12:58 1997  a sun  <asun@zoology.washington.edu>

	* dir.c
	changed mark_inodes_deleted to dget/d_delete/dput the dentry
	instead of just dropping it. the bytes available should now
	be updated properly upon deletion.

Wed Dec 10 00:01:25 1997  a sun  <asun@zoology.washington.edu>

	* dir.c
	changed mark_inodes_deleted to drop the dentry instead of 
	just deleting it. 

	TODO: bytes available aren't being properly updated when a
	resource fork gets deleted.

Mon Dec  8 23:22:40 1997  a sun  <asun@zoology.washington.edu>

	* dir_cap.c, dir_nat.c, dir_dbl.c, dir.c
	* hfs.h, linux/hfs_sysdep.h, linux/hfs_fs_i.h
	Added code to drop ({dbl,cap,nat}_drop_dentry) invalid
	dentries when creating or moving a file.

	* inode.c
	Added code to delete cached dentries when a file gets deleted.

	* current yuckiness: there's an extra hfs_cat_put somewhere. it's
	harmless but bothersome.
	
Thu Dec  4 00:14:03 1997  a sun  <asun@zoology.washington.edu>

	* dir.c, dir_cap.c, dir_nat.c, file.c, file_hdr.c, inode.c,
	* linux/{hfs_sysdep.h, hfs_fs.h}, version.c:
	Completed first code dentrification sweep. It mounts! It copies!
	It dcaches!

	Fixed the 30-year time warp with afpd.

	* TODO, trans.c:
	Don't mangle the name .AppleDesktop under fork=netatalk.

Mon Feb  3 23:18:45 1997  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* inode.c:
	Make header files always writable when the afpd mount option is given.
	Otherwise it is impossible to unlock a locked file.

	* TODO, inode.c:
	Let afpd think chmod() always succeeds, so "New Folder" works right.

	* super.c:
	The 'afpd' mount option now makes 'fork=n,names=n' the default.

	* TODO:
	List the current known afpd-compatibility problems as bugs.

	* file_hdr.c:
	Make certain date changes through header files get written to disk.

Sat Feb  1 02:24:12 1997  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* mdb.c:

	* TODO, README.sgml:
	Optimistically document the hybrid CD problem as fixed.

	* part_tbl.c:
	Fix the partition code so at least some of the hybrid
	CDROMs that were previously rejected are now accepted.

	* hfs.h:
	Make fs_start a 32-bit integer rather than 16-bits.
	The 16-bit value would overflow if a partition started
	beyond the 32M mark (e.g. the Executor 2 Beta 1 CDROM).

	* extent.c:
	Fixed a typo in an error message.

Tue Dec 10 14:43:46 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* extent.c:
	Fixed serious bug in decode_extent() with handling of empty extents.

	* file.c:
	Rewrote hfs_getblk().
	It will no longer hang if hfs_extent_map() is buggy.
	Also halves the worst-case number of calls to hfs_extent_map().

	* extent.c:

	* file_hdr.c:
	Implement hdr_write() and hdr_truncate()!!

	* hfs_fs_i.h, inode.c:
	Make hdr_layout per-inode (not per-file) so hdr_truncate() will work.

	* file.c, hfs.h, catalog.c, extent.c, balloc.c:
	hfs_extent_adj() now uses fork->lsize to determine the target file size.

Sun Sep 15 07:55:24 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* README.sgml, trans.c:
	Prevent creation of files & directories with '\0' or ':' in their names.

	* string.c, hfs_fs.h, hfs.h, dir_dbl.c, dir_nat.c, dir_cap.c:

	* inode.c:
	Small clean up of HFS_FIL_LOCK handling.

	* inode.c:
	Fix notify_change() not to accidentally make metadata executable.

	* inode.c:
	Return to old behavior where MdDat = i_mtime.

	* dir_dbl.c:
	Fix serious bug in hfs_dbl_readdir() that would lock-up access to a
	directory if one tried to write to a directory they had previously read.

	* file.c:
	Fix hfs_do_write() to adjust the fork's 'lsize' if it changed.

	* inode.c, file_cap.c:

	Any size changes will last only until the next iput() of the inode.
	Truncating a header file doesn't yet truncate the resource fork.

	* README.sgml:
	Note that it compiles on m68k machines, but needs more testing.

	* hfs_sysdep.h, Makefile:
	Changes to compile unmodified on m68k (and possibly other machines).

	* dir_cap.c:
	hfs_cap_readdir() was mistakenly producing .rootinfo entries for
	the .finderinfo and .resource subdirectories of the root directory.

	* inode.c:
	A directory's i_size was too small by 1 under CAP, so hfs_cap_readdir()
	would omit the last directory entry.  i_nlink was also too large by 1.

Sun Sep  8 12:56:06 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* file_hdr.c:
	Rewrite hdr_read() to be more efficient and to deal correctly with

	Repair and improve CAP support.

	* catalog.c:
	Oops! The BkDat for new files and directories was in 1972 when
	it should have been in 1904 (not that it matters that much).

	* inode.c:
	The HFS MdDat should be the larger of the i_mtime and i_ctime.

	* README.sgml:
	Change 'm_time' to 'i_mtime'.

Wed Sep  4 13:27:35 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* version.c, README.sgml:
	Bump version up to "0.7.1".

	  bfind.c, bnode.c, balloc.c:
	Make hfs_buffer a pointer to a buffer_head, rather than a buffer_head.

	* hfs_fs.h, dir_cap.c, dir_dbl.c, dir_nat.c, dir.c:
	Add a mknod() entry to the inode_operations for normal directories.
	All it is good for is letting root create regular files.

	* file_dbl.c, file_nat.c, file.c, file_cap.c, dir_cap.c, dir_dbl.c,
	  dir_nat.c:
	Add the missing NULL entries to the end of the file_operations.

Mon Aug 26 12:25:41 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* version.c, README.sgml:

	* README.sgml, version.c:
	Bump version up to "pre-0.7-6".

	* catalog.c:
	Fix a deadlock problem in catalog readers/writers locking.

	* bins_del.c:
	hfs_bnode_update_key() was still corrupting the header node sometimes.

	* catalog.c, dir.c:

	* hfs_fs.h, dir_cap.c, dir_dbl.c, dir_nat.c:
	Mangle the names as first step in hfs_{cap,dbl,nat}_lookup().
	Use the new hfs_streq() to catch mixed case matches to the special
	files and directories in hfs_{cap,dbl,nat}_lookup().
	Store reserved names only once.

	* dir.c, hfs.h, string.c:
	Implement hfs_streq() which tests for string equality more
	rapidly than hfs_strcmp() by checking for equal length first,
	and use it when checking for reserved names.

	* inode.c, TODO, dir_cap.c, dir_dbl.c, README.sgml:
	Provide the metadata for the root directory for the CAP and AppleDouble
	schemes in the files ".:rootinfo:" and "%RootInfo", respectively.

	* TODO:
	Add AppleShare support to the list of goals.

	* trans.c, super.c, hfs_fs.h, README.sgml:

	and remove redundant errors from the callers.

	* hfs_sysdep.h, mdb.c, super.c, file.c, hfs.h, hfs_btree.h, catalog.c,
	  extent.c, btree.c, balloc.c, bfind.c, bnode.c:

	Fix definition of HDRS variable.

	* README.sgml, version.c:
	Bump version up to "pre-0.7-1".

	Implement a portable set of buffer operations in hfs_sysdep.h

	* TODO:
	Remove note about separating header files into two parts.

	only file that actually uses it.

	* balloc.c:
	Replace use of hfs_getblk() in balloc.c with a local function
	(get_new_node()) that doesn't retry, since B-trees can't shrink.

	* hfs.h, hfs_btree.h, hfs_sysdep.h, mdb.c, extent.c:
	Make hfs_buffer a typedef.

	* inode.c, hfs.h, hfs_sysdep.h, dir.c:
	Change hfs_sysentry to a typedef.
	Rename 'sysentry' field of (struct hfs_cat_entry) to 'sys_entry'.

	* super.c, mdb.c, catalog.c:
	Rename hfs_cat_sync() to hfs_cat_commit() and call it
	from hfs_mdb_commit() rather than from hfs_write_super().

	* catalog.c, file.c:
	Minimize the calls to hfs_mdb_dirty().   Now called when:
	1) A buffer holding a volume bitmap block is dirtied.
	2) A dirty B-tree node is written back to the buffers.
	3) A dirty catalog entry is written back to the buffers.

	* hfs_sysdep.h, hfs.h:
	Make hfs_sysmdb a typedef.

Sun Aug 11 08:46:10 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	as a portable call to produce a device name.

	* super.c, hfs.h, mdb.c:
	Rename hfs_mdb_read() to hfs_mdb_get(), and don't take a
	'sys_mdb' argument.  That's the callers responsibility.

	Remove the pointless file sysdep.c

	* README.sgml:
	Clean up the "System Requirements" section.

Sat Aug 10 22:41:24 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	  file_cap.c, file_dbl.c, file_nat.c, hfs.h, file.c, dir_nat.c,
	  extent.c, dir.c, dir_cap.c, dir_dbl.c, catalog.c, bnode.c, brec.c,
	  btree.c, binsert.c, bitmap.c, bitops.c, bfind.c, bins_del.c,
	  Makefile, balloc.c, bdelete.c:
	Includes the hfs.h that was missing from the previous check in.
	MAJOR include-file cleanup:
		hfs_btree.h merged into hfs.h
		hfs_btree_private.h renamed hfs_btree.h
		sysdep.h renamed hfs_sysdep.h

	* sysdep.h, super.c, mdb.c, hfs_fs_sb.h, hfs_fs.h, file.c, extent.c,
	  catalog.c, bnode.c, bitmap.c:
	Make the field 's_mdb' in (struct hfs_sb_info) a pointer to
	the MDB, rather than the actual MDB.  This allowed the definition
	of (struct hfs_mdb) to be moved from hfs_fs_sb.h to hfs_fs.h.

	* ccache.c, hfs_fs.h, Makefile, catalog.c:
	Merged ccache.c and catalog.c into the latter.

	* hfs_fs.h, dir_dbl.c, dir_nat.c, ccache.c, catalog.c, dir_cap.c:
	Make hfs_cat_next() return the CNID and cdrType of the entry.

	depend on the structure of a catalog record on disk.

	* dir.c, hfs_fs.h, catalog.c:
	Replace hfs_cat_new_{file,dir}() with hfs_cat_{create,mkdir}()
	which are wrappers for what used to be hfs_cat_create().

	* hfs_fs.h, mdb.c, super.c, Makefile:
	Split super.c into super.c (Linux stuff) and mdb.c (MDB stuff).

	* super.c, hfs_fs_sb.h:
	Add the MDB field 'drAtrb' to (struct hfs_mdb) as the field 'attrib'.

	* hfs_fs_sb.h, super.c:
	Split hfs_read_super() into hfs_read_super() and hfs_mdb_read().

	* super.c, hfs_fs_sb.h:
	Remove the unneeded 'hs' field from (struct hfs_mdb).

	* TODO:
	Remove item about hfs_notify_change() needing to update metadata.

	* inode.c, hfs_fs.h, hfs_fs_sb.h, file_cap.c, file_dbl.c, file_nat.c,
	  file.c, dir.c:
	Add a flags argument to hfs_{cap,dbl,nat}_buildmeta() so that
	it only builds the parts that are currently out-of-date.
	Call hfs_{cap,dbl,nat}_buildmeta() through hfs_update_meta()
	in hfs_notify_change() and hfs_rename() to update the metadata.

	* dir.c:
	Make test for normal dir in update_dirs_{plus,minus}() more explicit.

	* inode.c, file_cap.c, file_dbl.c, file_nat.c, dir_dbl.c, dir_nat.c,
	  file.c, README.sgml, dir_cap.c:
	Resolve the "meta-data" vs. "metadata" rivalry in favor of the latter.

	* btree.c:
	Simplify some debugging code.

	* hfs_btree_private.h, bnode.c, btree.c, balloc.c:
	Put the in-core copy of the header node IN the
	B-tree structure rather than just a pointer to it.

	* hfs_btree_private.h, btree.c, bnode.c:
	Have hfs_btree_commit() call hfs_bnode_commit()
	to commit the header and root nodes.

	* hfs_fs.h, super.c, hfs_btree_private.h, btree.c, hfs_btree.h,
	  balloc.c:
	Change hfs_commit_mdb() to hfs_mdb_commit().
	Make hfs_mdb_commit() call hfs_btree_commit().
	Move code to update B-tree size and extent
	from hfs_btree_extend() to hfs_btree_commit().
	Make hfs_btree_extend() call hfs_mdb_commit().

	* super.c:
	Change hfs_commit_super() to hfs_commit_mdb().

	* btree.c, bnode.c, bfind.c:
	Fixed up broken debugging code and error messages.

	* super.c, hfs_btree_private.h, btree.c, hfs_btree.h, bdelete.c,
	  binsert.c, balloc.c:
	Now use write-back caching of B-tree header fields.

	* hfs_fs.h:
	Get rid of the add{16,32}() inlines as they are no longer used.

	* hfs_btree_private.h, binsert.c, btree.c, bdelete.c, bfind.c, balloc.c:
	All the needed fields of the B-tree header are
	now cached for reading, but not yet writing.

	* TODO:
	Remove "Implement write count" from TODO list.

	* file.c, super.c, bnode.c:
	Implement write count.

	* catalog.c:
	Fix directory entry counting in hfs_cat_move().

	* balloc.c:
	Simplify hfs_btree_extend(), since the allocation
	request will get rounded up to the clumpsize.

	* extent.c:
	Honor clumpsize when allocating blocks to files.

	* file_cap.c, file_dbl.c, file_nat.c, super.c, dir.c, file.c,
	  ccache.c, catalog.c, balloc.c:
	Mark 44 functions in need of commenting.

	* hfs_fs_sb.h, super.c, extent.c, hfs_fs.h, ccache.c, btree.c, balloc.c:
	Record clumpsize in allocation blocks rather than 512-byte blocks.

	* sysdep.h, super.c, TODO, balloc.c, hfs_fs_sb.h:
	Now updates the backup MDB when a B-tree grows.

	* extent.c:
	hfs_extent_free() had test against NULL backward.
	The result is that access to a file with extents in the extents
	B-tree would result in an infinite loop in hfs_cat_put().

	* hfs_fs_sb.h, super.c, hfs_fs.h:
	Reorganize partition map code to get size of partition
	in preparation for dealing with the alternate MDB.

Fri Aug  9 03:25:13 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* Makefile:
	Add make rules for README.{ps,info}

	* README, README.sgml, DOC, FAQ, Makefile, .cvsignore, 
	Merge CHANGES into ChangeLog.
	Merge DOC, FAQ and README into README.sgml.
	Add make rules for building README.{txt,dvi}

	* BUG_INFO, Makefile:
	Added a BUG_INFO script which attempts to collect some useful
	information which I'd like to see in every bug report I receive.

	* Makefile, version.c:
	Added version.c which contains a version string.

Thu Aug  8 21:48:24 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* trans.c:
	Fix Latin-1 -> Macintosh filename mapping to change colons to pipes.

	* trans.c:
	Fixed Mac->Latin-1 translation to behave as documented for the
	extended 8-bit characters without corresponding Latin-1 characters.

	* inode.c, super.c, file.c, hfs_fs_i.h, hfs_fs_sb.h, DOC:
	Added a conv={binary,text,auto} mount option similar to that of the
	msdos, hpfs and iso9660 filesystems, but applying only to data forks.
	As compared to those filesystems, HFS has the advantage that only a
	single CR need be converted to a NL, rather than a CR/NL sequence, so
	it is quite safe to seek in the file.
	Additionally the 'Type' field is far more reliable indicator of text
	files than a file extension.

	* super.c:
	Simplified parsing of mount options.

	* super.c:
	Oops!  The part=<n> mount option was being parsed in octal!

	* TODO:
	Remove "case=lower" from the list of goals.

	* super.c, hfs_fs.h, hfs_fs_sb.h, string.c, dir_dbl.c, dir_nat.c,
	  dir_cap.c, DOC:
	Resurrect the case={asis,lower} mount option.

	* dir.c:
	Simpler test for "normal" directory in update_dirs_{plus,minus}().

	* hfs_fs_sb.h, super.c, dir.c, hfs_fs.h, catalog.c, DOC:
	Add mount options to specify what Type and Creator will be used for
	new files and change the default from NULLs to "????".

Wed Aug  7 11:32:22 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* catalog.c:
	In hfs_cat_next() use entry->cnid rather than the key of the initial
	brec to identify the end of the directory.

	* README:
	Update for pre-0.7 version.

	* hfs_fs.h:
	Create versioned module if CONFIG_MODVERSIONS is set in linux/config.h

	* TODO:
	Note need for special steps for unaligned accesses on some machines.

	* FAQ:
	Added Q0: What is HFS?
	Added Q7: Does hfs_fs work w/ 400k and 800k diskettes?
	Brought Q6 (about writability) up to date.
	Made a few other answers more verbose.

Tue Aug  6 00:58:46 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* Makefile:
	Changed 'snapshot' rule to include cvs tag command.

	* hfs_fs.h, dir_cap.c, dir_dbl.c, dir_nat.c, catalog.c, ccache.c:
	Implemented readers half of dir locking scheme so readdir() should
	produce consistent results and count_dir_entries() is not race prone.

	* catalog.c:
	hfs_cat_move() was calling hfs_cat_decache() after changing
	the key rather than before, corrupting the hash lists.

Mon Aug  5 14:03:46 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* hfs_fs.h, catalog.c:
	Implemented the writers half of a locking scheme for directories.

	* inode.c:
	Fixed a serious bug in hfs_notify_change() that would allow a chmod()
	on directory meta-data and would cause the directory inode (if it was
	in memory at the time) to change into a file inode.

	* inode.c:
	Fixed a problem with write permissions on directory meta-data.

	* dir_dbl.c, dir_nat.c, dir_cap.c:
	hfs_{cap,dbl,nat}_readdir() now return the correct value in the 'd_ino'
	field of the dirent for all cases, something I think has always been
	done incorrectly until now.

	* dir_nat.c, inode.c, dir_cap.c:
	In hfs_{cap,nat}_lookup() take advantage of the
	'file_type' field of (struct hfs_inode_info).

	* TODO:
	Removed two accomplished goals (rename() and improved readdir()).

	* inode.c, dir_dbl.c, dir_nat.c, hfs_fs_i.h, dir.c, dir_cap.c:
	Rewrite hfs_{cap,dbl,nat}_readdir() to take advantage of hfs_cat_next().
	They now use a uniform 'i_size' for all inodes for a given directory.
	This simplifies update_dirs_{plus,minus}() and eliminates the need for
	the 'file_size' and 'dir_link' fields of (struct hfs_inode_info).
	For the CAP and Netatalk schemes the meta-data directories are now the
	last entries rather than coming just after '.' and '..'.  This is in
	preparation for the day when we can write to the files in those
	directories, and ensures that when using 'tar' to copy HFS filesystems
	the file or directory will be created before the meta-data is written.
	Otherwise we could be stuck writing meta-data and not knowing if it is
	for a file or a directory!

	* ccache.c:
	Updated count_dir_entries() for new hfs_cat_next().

	* hfs_fs.h, catalog.c:
	hfs_cat{nth,next}() no longer take a 'types' argument,
	so they now return all entries.
	hfs_cat_next() now uses the ParID of the key to detect
	the end of the directory.
	hfs_cat_nth() now accepts n=0 as a valid input, requesting the thread.

	* trans.c, string.c, super.c, dir_nat.c, hfs_fs.h, dir.c, dir_cap.c,
	  dir_dbl.c, catalog.c:
	Rename (struct hfs_cname) to the more appropriate (struct hfs_pstr).

	* hfs_fs.h, hfs_btree.h:
	Move some constants from hfs_fs.h to hfs_btree.h

	* bdelete.c, hfs_btree.h:
	Remove hfs_bdelete_brec() from public B-tree interface.

	* hfs_btree_private.h, hfs_fs.h, btree.c, hfs_btree.h, bnode.c, brec.c,
	  bfind.c, bins_del.c, binsert.c, balloc.c, bdelete.c, Makefile:
	Split B-tree stuff into public and private parts:
		brec.c split into bfind.c and brec.c
		hfs_btree.h split into hfs_btree.h and hfs_btree_private.c

	* inode.c:
	The tests and sets of the HFS_FIL_LOCK bit where all reversed!

	* hfs_fs.h, ccache.c:
	Redo some ccache stuff, removing the 'error' field from
	(struct hfs_cat_entry) and ensuring that hfs_cat_put()
	will not sleep on an uninitialized entry.

Sun Aug  4 23:43:28 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* sysdep.h:
	Change swap{16,32}() back to macros since hton[ls]() are functions.

	* hfs_fs.h, ccache.c:
	Use only lowest order byte of parent CNID in hashing a catalog key.

	* bdelete.c:
	The "improved" bdelete() was TOO paranoid looking for missing parents.

	* ccache.c:
	Get rid of pointless swap16const(0).

	* hfs_fs.h, inode.c, extent.c, ccache.c, dir_cap.c, dir_nat.c,
	  binsert.c, catalog.c:
	Store cnid and associated constants in big-endian byte order.
	This reduces the number of byte-order swaps required.

	* sysdep.h:
	Make swap32() and swap16() inline functions.

	* dir_nat.c, dir_cap.c, dir_dbl.c:
	Added hfs_rename() to the inode_operations for normal directories.

	* dir.c, hfs_fs.h:
	Added hfs_rename() and cleaned up hfs_{create,mkdir,unlink,rmdir}().

	* catalog.c:
	Added the missing check for moving a directory into itself.

	* catalog.c, ccache.c, hfs_fs.h:
	Implement a nearly ideal hfs_cat_move().
	It still needs to prevent moving a directory into itself.
	The functions hfs_cat_{create,delete,move}() still need work with
	respect to their atomicity (especially vs. readdir).

	* bdelete.c:
	Fixed a serious bug in hfs_bdelete_brec() that would yield a corrupted
	b-tree when the first record in a bnode was deleted.
	Made bdelete() more aggressive when checking for missing parents.

Sat Aug  3 06:11:50 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* btree.c, super.c:
	Fixed a problem that caused a kernel oops when no HFS filesystem
	is found.

Wed Jul 24 13:06:12 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* catalog.c:
	Remove race in hfs_cat_create() that could overflow directory valence.

	* catalog.c:
	Fix hfs_cat_create() so the parent directory doesn't get deleted
	out from under it.  Otherwise we could have created files and
	directories in deleted directories.

	* hfs_fs.h, dir_cap.c, dir_dbl.c, dir_nat.c, catalog.c, ccache.c:
	Redo hfs_cat_{next,nth}() in terms of which entry types to
	allow, rather than which to skip.

	* catalog.c:
	The function hfs_cat_create() would fail to hfs_cat_put(entry) if
	the 'record' argument was invalid or if the 'result' argument was NULL.

	* dir.c:
	The functions hfs_{create,mkdir,unlink,rmdir} all failed to
	call iput() when their arguments conflicted with a reserved name.

	* catalog.c, hfs_fs_sb.h:
	Start over on rename().  Still unfinished.
	Fix silly bug in hfs_cat_create() that made it always fail.

	* ccache.c:
	Fix byte-order bug in write_entry().

Tue Jul 23 12:12:58 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* dir_dbl.c, dir_nat.c, hfs_fs.h, dir.c, dir_cap.c:
	Remove the macros KEY() and PARENT() since the key is now easy
	to access through the catalog entry.
	Replace the macros NAME{IN,OUT}() with inline functions
	hfs_name{in,out}() to gain type checking of arguments.

	* catalog.c:
	Remove the macro TYPE().

	* inode.c, file_dbl.c, file_nat.c, file.c, file_cap.c:
	Remove the #define's of the unused macro KEY().

	* hfs_fs.h, dir_cap.c, dir_dbl.c, dir_nat.c, catalog.c, dir.c:
	Replace hfs_lookup_parent() in dir.c with hfs_cat_parent() in catalog.c.
	This new function performs locking to protect against rename() changing
		the parent during I/O.
	It is also intended for use with files as well as directories.
	Change hfs_{cap,dbl,nat}_lookup() to use the new function.

	* dir.c, hfs_fs.h, catalog.c:
	Remerge hfs_cat_{create,mkdir}() into hfs_cat_create() and resurrect
		hfs_cat_new_{file,dir}().
	Fix hfs_cat_{create,delete} to use the improved catalog cache for
		locking in place of directory-level create/delete locks.
	Fix hfs_{create,mkdir}() to use the new hfs_cat_create().

	* hfs_fs.h, ccache.c:
	Rewrite parts to remove need for specialized create/delete locking.
	Use new case-independent hash function.
	Fix bug in hfs_cat_get() that would read an entry w/o locking it.
	Call hfs_relinquish() before retrying a deleted entry in hfs_cat_get.
	If there is a read error, then don't retry in hfs_cat_get().
	Remove unused 'version' field from (struct hfs_cat_entry).

	* sysdep.h:
	Add hfs_relinquish(), a system-independent alias for schedule().

	* hfs_fs.h, string.c:
	Add hfs_strhash(), a simplistic case-independent hash function.

	* hfs_fs.h, inode.c:
	Make hfs_iget() an inline function.

	* TODO:
	Add a few goals and removed those that have been achieved.

	* Makefile:
	Add ccache.c to list of source files.
	Add rule for *.s files and include them in the 'clean' rule.

Wed Jul 17 17:22:45 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* sysdep.h, trans.c, string.c, super.c, hfs_fs_i.h, hfs_fs_sb.h,
	  inode.c, hfs_btree.h, hfs_fs.h, file_dbl.c, file_nat.c, extent.c,
	  file.c, file_cap.c, dir_dbl.c, dir_nat.c, ccache.c, dir.c,
	  dir_cap.c, btree.c, catalog.c, bnode.c, brec.c, balloc.c:
	Total rewrite of the inode-handling stuff to be centered around
	a catalog entry cache (ccache.c).  This results not only in a far
	more sensible way of doing things, but also removed many race
	conditions. (The source and object code both got smaller too!)
	Many small "undocumented features" were also fixed.
	Replace HFS_CNAME with (struct hfs_cname).
	rename() has been temporarily abandoned.

Thu Jul 11 01:14:38 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* dir.c:
	As written hfs_lookup_parent() had two overlapping read requests
	in the catalog tree.  This could have led to deadlock.

Wed Jul 10 09:27:00 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* catalog.c, hfs_fs.h, bdelete.c:
	More work on getting rename() fleshed out.  Still not done.
	Before I can finish it looks like I'll need to build a
	mechanism for exclusive access to the catalog tree.  There
	just doesn't seem to be any other way to get proper POSIX
	semantics without a bunch of race conditions elsewhere.

	* hfs_fs.h, inode.c, dir_cap.c, dir_dbl.c, dir_nat.c, catalog.c:
	More work on the still incomplete rename() code.
	Merge hfs_cat_add_{dir,file}() into hfs_cat_create().
	Add file-thread support to hfs_cat_{create,delete,rename}.

Tue Jul  9 09:43:15 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* inode.c, dir_dbl.c, dir_nat.c, extent.c, dir_cap.c:
	The indirect (struct hfs_file) was causing blocks not to be freed
	when files where deleted, and an omission in hfs_put_inode() was
	preventing the inode from getting freed.  Both are now fixed.

	* hfs_fs.h, dir_dbl.c, dir_nat.c, hfs_btree.h, catalog.c, dir_cap.c,
	  bdelete.c:
	Made unlink() and rmdir() more race resistant and did some more
	work on the still incomplete code for rename().

	* btree.c, bnode.c:
	There was a serious race condition in the bnode cache, so
	hfs_bnode_find() is now modeled after Linus's inode cache.

Mon Jul  8 10:33:38 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* hfs_fs_i.h, inode.c, file_cap.c, file_dbl.c, file_nat.c, dir_dbl.c,
	  dir_nat.c, file.c, dir.c, dir_cap.c:
	More changes to layout of (struct hfs_inode_info).

	* super.c, inode_cap.c, inode_dbl.c, inode_nat.c, inode.c, hfs_fs_i.h,
	  hfs_fs_sb.h, file_nat.c, hfs_fs.h, file.c, file_cap.c, file_dbl.c,
	  Makefile, catalog.c:
	Implemented new layout for (struct hfs_inode_info) resulting in the
	elimination of lots of duplicated code for hfs_*_write_inode(),
	hfs_*_put_inode() and *_open() functions.
	Merged inode_*.c files back into inode.c.
	Not fully tested.

	* TODO:
	Add a few more of my goals to the list.

	* README:
	Documentation updates.

	* inode_nat.c, inode_cap.c, inode_dbl.c, inode.c, hfs_fs.h, hfs_fs_i.h,
	  file.c, file_cap.c, file_dbl.c, file_nat.c, catalog.c:
	(struct hfs_file) and metadata are read when file is opened or
	truncated and are released by iput().

Sun Jul  7 23:55:43 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* inode_nat.c, inode_cap.c, inode_dbl.c, inode.c, dir_nat.c, hfs_fs.h,
	  hfs_fs_i.h, dir_cap.c, dir_dbl.c, catalog.c, dir.c:
	(struct hfs_dir) is now inside (struct hfs_inode_info) once again.

	* inode_nat.c, super.c, inode_cap.c, inode_dbl.c, inode.c, file_nat.c,
	  hfs_btree.h, hfs_fs.h, extent.c, file_cap.c, file_dbl.c, dir_nat.c,
	  dir_cap.c, dir_dbl.c, btree.c, catalog.c, dir.c, bpath.c, brec.c,
	  bins_del.c, binsert.c, bnode.c, bfind.c, balloc.c, bdelete.c,
	  Makefile:
	Remerged (struct hfs_bpath) and (struct hfs_brec), merging the
	files bfind.c and bpath.c as a resurrected brec.c.

Sat Jul  6 21:47:05 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* inode_cap.c, inode_dbl.c, inode_nat.c, inode.c, hfs_fs.h, hfs_fs_i.h,
	  file_cap.c, file_dbl.c, file_nat.c, hfs_btree.h, dir_nat.c, extent.c,
	  dir.c, dir_cap.c, dir_dbl.c, btree.c, catalog.c, bfind.c, bpath.c,
	  binsert.c, bdelete.c:
	Renamed (struct hfs_brec_key) to (struct hfs_bkey).

Tue May 28 07:53:24 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* inode_cap.c, catalog.c:
	Spelling fixes.

	* inode_nat.c, super.c, inode_cap.c, inode_dbl.c, inode.c, hfs_fs.h,
	  hfs_fs_i.h, hfs_fs_sb.h, file.c, file_dbl.c, file_nat.c, dir_dbl.c,
	  dir_nat.c, extent.c, dir.c, dir_cap.c, catalog.c:
	Structures got too big, so I had to add a layer of indirection
	to (struct hfs_inode_info).
	This means we must clear_inode() in inode_put().

Mon May 27 01:32:42 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* catalog.c, file_cap.c:
	Some sizeof() stuff now uses variable not type.

	* hfs_fs.h:
	Make HFS_I() and HFS_SB() inline to gain type checking.

Sun May 26 13:34:17 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* dir_nat.c:
	Oops.  Had left some debugging printk()s in place.

	* file_dbl.c, file_nat.c, file_cap.c:
	Cleaned up variable names for consistency.

	* hfs_fs_sb.h:
	Add a couple 'const's to function typedefs.

	* hfs_fs.h:
	Add and update function prototypes.
	Cleaned up type names.
	Fix debugging malloc code.
	Add hfs_iget_by_name() as an inline function.

	* sysdep.h:
	Remove extra semicolon from macro definitions.

	* super.c:
	Use new hfs_iget_by_name() to get root inode.

	* extent.c:
	Cleaned up some variable naming for consistency.

	* catalog.c:
	Added (untested) code for hfs_cat_move_file().

	* catalog.c:
	Fix one missed call to hfs_cat_build_key().
	Make hfs_cat_add_{file,dir}() take a cat_entry as an argument.
	Add hfs_cat_new_{file,dir}() to generate new cat_entry's.

	* dir_dbl.c, dir_nat.c, dir.c, dir_cap.c:

Tue May 21 07:02:34 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* bnode.c:
	Attempt to read invalid bnode would have led to an infinite loop under
	certain circumstances.  One way to cause this was with an invalid
	partition table which points beyond the end of the device.

Sat May 11 12:38:42 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* sysdep.h, sysdep.c, inode_dbl.c, inode_nat.c, super.c, inode_cap.c,
	  inode.c, hfs_fs.h, hfs_fs_i.h, hfs_fs_sb.h, file_dbl.c, file_nat.c,

Tue May  7 11:28:35 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* super.c, sysdep.c, sysdep.h, inode_cap.c, inode_dbl.c, inode_nat.c,

Fri May  3 20:15:29 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* super.c, inode_dbl.c, inode_nat.c, inode.c, inode_cap.c, extent.c,
	  hfs_fs.h, hfs_fs_i.h, dir_dbl.c, dir_nat.c, catalog.c, dir.c,
	  dir_cap.c, bpath.c, btree.c, binsert.c, bnode.c:
	"FID reform": 'fid' became 'cnid' (Catalog Node ID), and is now
	a field in (struct hfs_file).  The new name is more consistent
	with Apple's documentation.  The presence of 'cnid' in (struct
	hfs_file) help move more of the code toward OS-independence.

	* inode_nat.c, super.c, trans.c, inode.c, inode_cap.c, inode_dbl.c,
	  hfs_fs.h, file_cap.c, file_dbl.c, file_nat.c, dir_nat.c, extent.c,

Wed Apr 24 13:20:08 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

	* hfs_fs.h, bnode.c, hfs_btree.h:
	Fixed a couple more type size assumptions.

	* hfs_fs.h, balloc.c, bitmap.c, bitops.c:
	"Portable" bitmap handling was wrong for just about everything but
	the i386 and the "inverse big-endian" bit ordering that I thought
	the m68k port was using.  It seems the m68k port is now using standard
	big-endian bit-numbering conventions.
	This code is now correct for the standard big- and little-endian bit
	orderings. (which should cover all Linux systems?)
	Also no longer assumes sizeof(long) == 4, though that might still be
	a problem in other parts of the code.

	HFS_BFIND_DELETE should require exact match.

	* dir.c:
	Set "record in use" bit of filFlags for new files.

	* inode.c:
	Was doing the wrong thing with i_ctime.

	* dir_nat.c, dir_cap.c, dir_dbl.c:

	* extent.c:
	Since 1.3.45 truncate() has locked the file, so there is no need

	* extent.c:
	hfs_file_extend() now more "robust", but new_extent() is still

	* btree.c:
	hfs_btree_{init,free}() modified for changes to struct:
		'file' and 'cache' moved back into structure
		file.inode initialized to reduce special cases
	hfs_btree_init() gets pointer to size in MDB instead of size.
	Added hfs_btree_extend() (incomplete and uncommented).

	* bnode.c:
	hfs_bnode_{alloc,free}() moved to separate file.
	Removed 'const' from some function arguments
		due to change in struct hfs_btree.
	hfs_bnode_lock(): added WRITE/RESRV->READ transition.

	* brec.c:
	hfs_brec_get_{root,child}() now take a 'keep_mask' argument
		indicating when to keep ancestor nodes, and store
		information about why ancestors were kept.
	HFS_BFIND_CHAIN eliminated in favor of HFS_BFIND_{INSERT,DELETE}
		which are now implemented using 'keep_mask'.
	Added hfs_brec_relse_one() that doesn't release ancestors.

	* bins_del.c:
	Lots of rewrites to cleanup insertion.
	Now tries to extend tree before insertion starts.
	binsert() iterative rather than recursive.
	No point in keeping track as it is still not "stable".

	* balloc.c:
	New file: started with hfs_bnode_{free,alloc}()
	Added hfs_bnode_init() to initialize a newly allocated bnode.
	hfs_bnode_free():
		Renamed hfs_bnode_bitop().
		Can set or clear a specified bit.
		Gets bitmap sizes from nodes directly.
	hfs_bnode_alloc():
		Returns actual node, calling hfs_bnode_init().
		Gets bitmap sizes from nodes directly.

	* bfind.c:
	Removed obsolete comment from hfs_bsucc()
	Removed 'const' from tree arg of hfs_bfind()
		due to changes in struct hfs_btree.

	* Makefile:
	Added new file: balloc.c

	* Start of detailed CVS logging.

Mar 09, 1996: snapshot-09Mar96 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	NOT AN OFFICIAL RELEASE
	Fixed up debugging code that was broken by split of btree.c
	Added debugging kmalloc/kfree
	Fixed memory leak in hfs_bnode_relse()

Mar 08, 1996: snapshot-08Mar96 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	NOT AN OFFICIAL RELEASE
	now reset blocksize on device when done.
	hfs_binsert done (except for the full tree case).
	btree.c split up into manageable pieces (need to sort out hfs_btree.h)

Feb 26, 1996: snapshot-26Feb96 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	NOT AN OFFICIAL RELEASE
	Some writability.
	Bug with multiple opens of meta data fixed.
	Netatalk support no longer considered experimental.

Virtually everything has changed, so I've lost track here.

Nov 16, 1995: snapshot-16Nov95 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	NOT AN OFFICIAL RELEASE
	Still more comments.
	btree.c back to 80 columns.  will do same to other files soon.
	Starting with btree.c have begun to put file contents into some
		sort of standard order.
	Moved metadata reading to VFS open() routine and now free it in
		the VFS release() routine.  Much cleaner than the old way.
	Unified hfs_iget by shifting scheme-dependent code into a function
		pointer in the superblock.  This could/should be shifted to
		a VFS read_inode() routine if that can be done cleanly.
	Probably lots of other changes; I've lost track.

Nov 05, 1995: version 0.5.3 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	NOT AN OFFICIAL RELEASE
	1.2.x compatibility removed
	Added lots of comments to btree.c and cleanup some code.  The result
		is that the source file doubled in size while the object
		file dropped in size by 20%.
	Added some comments to super.c and dir.c as well.
	Cleaned up some stuff in dir.c adding some additional error checking
		and moving closer to using a unified hfs_iget by migrating
		common code into lookup_parent().
	Changed btree.c to use a separate bnode cache per filesystem.
	Renamed a bunch of the bnode functions in btree.c

Jun 29, 1995: version 0.5.2 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	BUG FIX and 1.3.x-compatibility release.
	Will compile under 1.2.x or 1.3.x by changing one line in Makefile.
	Started adding magic numbers to structures for "safety".
	Don't strip internal symbols when linking or loading, as this made
		good bug reports rather difficult.
	Fixed a bug that could cause the fs to lock-up after trying to open
		a non-existent file.
	Fixed a bug that allowed files to appear truncated, when in fact it
		is still not possible to truncate a file.
	Added more/better comments to header files.
	Deal with volume and b-tree bitmaps in preparation for writing.
	Fixed readdir() to deal properly with the case where the directory
		changes while writing to user-space. (which can't yet
		actually happen, until directories are writable).

Jun 23, 1995: version 0.5.1 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	BUG FIX RELEASE
	Removed two debugging messages that didn't belong.
	Fixed a typo that prevented modified inodes from being written to disk.
	Added a missing line which prevented rmmod'ing sometimes.
	Added a missing line which caused errors when modifying .finderinfo or
		.resource under the CAP system.
	Added a notify_change() to keep mode bits sensible, and to cause
		changes to an inode to affect the data fork and resource fork
		of a file together.

Jun 22, 1995: version 0.5 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	Fixed a bug that was giving wrong values for i_blocks
	Partly writable (can only 'touch' existing files, so far)
	Removed case= mount option.  It will be back eventually.
	Can now deal with CDROMs (and hard disks?), many thanks to
		Holger Schemel for this work.
	Latin-1 filename conversion also due to Holger Schemel.
	Rewritten btree operations.

Feb 28, 1995: version 0.4 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	Requires Linux >= 1.1.94: depends on changes made to asm/byteorder.h
	Now using string comparison code donated by ARDI (see string.c)
	Code reorganized to use data structures more like ARDI's.
	More code reorganization to abstract the btree operations.
	Added the fork= mount option.
	Added AppleDouble support.  Executor, from ARDI, can now run programs
		from HFS filesystems mounted with the HFS module.

Jan 28, 1995: version 0.3 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	Major code reorganization.
	Known for certain to work ONLY on floppies.
	Started caching extents, so got faster on long file reads.
	Now compiles separate from kernel tree.
	Supports 5 filename conversion methods.
	Supports forks, using the method from CAP.
	All external symbols now start with HFS_ or hfs_

Jan 12, 1995: version 0.2 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	Should now work on all HFS volumes, but still only tested on floppies.
	Got smaller and faster with some code reorganization.
	Since Linus moved htons() and friends to an asm file, should now be
	 truly endian-independent, but still only tested on Intel machines.
	Requires Linux >= 1.1.77, since Linus moved htons().

Jan 05, 1995: version 0.1 hargrove@sccm.stanford.edu (Paul H. Hargrove)
	First release.
	1.44Mb floppies only
	no resource forks
	trivial name mangling only
	read only
	for Linux >= 1.1.75
