+		the msdos_inode_info, but the clear winner here is
+		the ext2_inode_info. So it does not change anything to
+		the total size of a struct inode.

+		I have not put it conditional. With the advent of loadable
+		file system drivers, it would be very easy to compile
+		a MsDOS FS driver unaware of UMSDOS and then later to
+		load a (then incompatible) UMSDOS FS driver.
