searching the cache twice when a block isn't in the
cache. If reads are larger than READ_DIRECT_SIZE, don't
let them go through the cache.
blocks to be erroneously marked as dirty, so they would
get written back to the disk before they are evicted from
the cache. Harmless, but it slows down e2fsck
significantly.
Disable certain tests that depend on the byteswapping functions
being present so that "make check" succeeds even if --disable-swapfs
is passed to the configure script.
support for loopback-mounted filesystems. Check /etc/mtab
if /proc/mounts doesn't turn up any mount flags, since
/etc/mtab has the loopback image filename, instead of
/dev/loop0. Also, check based on st_dev and st_ino, so
that if a relative pathname or a pathnames using symbolic
links are used, we can detect the the filesystem correctly
in those cases. (Addresses Sourceforge bug #619119)
don't try the FDFLUSH ioctl that was required for floppies
with older kernels. This avoids needless whining from the
MD device driver. (Addresses Sourceforge bug #545832).
wrong group_block to ext2fs_descriptor_block_loc if we're
using the backup superblock/block group descriptors.

the next block group.
the filesystem was created. It is set via mke2fs, and printed
via list_super2() (which is called by dumpe2fs).
Also, list_super2() will now print "n/a" if the last mount time
(s_mtime) is zero.
When byte-swapping a filesystem on a PPC architecture, byte-swap
the bitmaps since the historical big-endian ext2 variant had
byte-swapped bitmaps, and the ext2fs library assumes this. Otherwise
the regression test suite will fail...
using a non-zero hash version (i.e., half MD4 or TEA hash).
The hash version wasn't getting copied into dx_dir->hashversion and
this caused the kernel to treat all directories if they were using the
legacy hash, which was Bad.
superblock. Dumpe2fs can now print out these fields, and they
can be modified using debugfs's set_super_value command. Also added
to debugfs was the ability to set s_uuid and s_journal_uuid features
as well.
Fixed up confusion caused by bad parameter names for
get_fs_limits(). Added missing conversion of
volume->vol_size from sectors to bytes. Fix up error
returns for unsupported tasks as EINVAL, not ENOSYS.
Use logical names for the API version numbers, since
the ABI is much more dependent on the headers. Add
code to byte-swap the superblock if necessary.
Revert the shlibs hack.
Makefile.in: Remove inode_io.o from the standard object files
in libext2fs, and only build it if debugfs is enabled
(it requires fileio.o, which is only built if
--disable-debugfs isn't specified to configure).

a backwards incompatible change, but this should be OK since the kernel
MD4 ext3 code was only in the CVS tree, and hasn't generally escaped.
Add support for the TEA hash.
