Name       : QNX4 TODO list
Last update: 29-06-1998

    - qnx4_checkroot (inode.c), currently there's a look for the '/' in
      the root direntry, if so then the current mounted device is a qnx4
      partition. This has to be rewritten with a look for 'QNX4' in the
      bootblock, it seems to me the savest way to ensure that the mounted
      device is in fact a QNX4 partition.
      Done 20-06-1998, Frank. But some disks (like QNX install floppies)
      don't have 'QNX4' in their bootblock.
      
    - Bitmap functions. To find out the free space, largest free block, etc.
      Partly done (RO), Richard, 05/06/1998. Optimized 20-06-1998, Frank.
    
    - Symbolic links. symlinks.c have to be rewritten.
    
    - Extended files.
    
    - Complete write, unlink and truncate functions : the bitmap should be
updated.

    - Porting to linux 2.1.99+ with dcache support. 20-06-1998, Frank.
    
    - Don't rewrite the file_read function : use the generic_file_read hook,
      and write readpage instead. Done on 21-06-1998, Frank.

    - Write dinit and dcheck.

    - Solving the bugs.
    
    - Use le32_to_cpu and vice-versa for portability.
