The Lifetime writes field will probably not be stable as we add new
features to e2fsprogs, so filter it out to avoid spurious test failures.

Gcc is too stupid to realize that:
const char *usage="String which has no percent signs";
com_err(progname, 0, usage);
is OK. I refuse to bow to stupidity with:
com_err(progname, 0, "%s", usage);
but I will use the string directly for the sake of people who like to
build with -Werror=format-security.

E2fsck could to do more damage to a filesystem by trying to relocate
inode tables due to corrupted block group descriptors, and the
relocation could seriously damage the filesystem.
This patch enhances ext2fs_check_desk() so it detects more
self-inconsistent block group descriptors, including the cases where
e2sck might be tempted to relocate the inode table, and reports the
block group descriptors as invalid; this will cause e2fsck to attempt
to use the backup superblocks, which hopefully have not been trashed.

When calculating the number reserved blocks, use floating point for
better accuracy, since for big filesystems it really makes a
difference. In addition, mke2fs and tune2fs accepts a floating point
number from the user, so they should provide that level of accuracy.

With the new mke2fs changes the output of the

already have the file system. So erase the file system
before running mke2fs so that output remain as expected.

Provide mke2fs with a much more sophisticated system for controlling
configuration parameters of a newly created filesystem based on a
split filesystem and usage type system. The -t option to mke2fs was a
deprecated alias to -c; it now specifies a filesystem type (ext2,
ext3, ext4, etc.), while the -T option can now be a comma separated
usage list.

Never set the UNINIT_BLOCKS flag for the last group since the kernel
doesn't handle the case graefully if there is a full set of blocks in
each blockgroup marked UNINIT_BLOCKS. The kernel should be fixed up,
but in the meantime this avoids hitting the problem, and is more
consistent with lazy_bg not marking the last group UNINIT.

If a directory's i_size is bigger than the number of blocks, don't try
to allocate extra empty blocks to the end of the directory; there's no
real point to do that. Also, if a directory's i_size is not a
multiple of the blocksize, flag that as a mistake so it can be fixed.
This more elegantly addresses the problem which was found on Bas van
Schaik's filesystem.

The image contains an inode past the resize point with an inline xattr
value of "propervalue". It also contains deleted inodes which had the
xattr value "oldvalue".
When resize2fs moves the inode, it should copy the xattr as well, so
that post-resize we see "propervalue" not "oldvalue".
