Theodore Ts'o 1e0c8ca7c0 e2fsck: fix portability problems caused by unaligned accesses 
The on-disk format for the ext4 journal can have unaigned 32-bit
integers.  This can happen when replaying a journal using a obsolete
checksum format (which was never popularly used, since the v3 format
replaced v2 while the metadata checksum feature was being stablized),
and in the fast commit feature (which landed in the 5.10 kernel,
although it is not enabled by default).

This commit fixes the following regression tests on some platforms
(such as running 32-bit arm architectures on a 64-bit arm kernel):
j_recover_csum2_32bit, j_recover_csum2_64bit, j_recover_fast_commit.

README 

	This is the new version (1.46.2) of the second extended file
system management programs.

	From time to time, I release new versions of e2fsprogs, to fix
bugs and to make the utilities more robust.  You can always find
information about the latest version at the the e2fsprogs web page,
which is:

	http://e2fsprogs.sourceforge.net

	The INSTALL file has instructions on building and installing
e2fsprogs.  Provisions for building Red Hat RPMs and Debian dpkg files
are supplied as well.

	In case of bugs in these programs, please contact Ted Ts'o at
tytso@mit.edu or tytso@alum.mit.edu.  See the e2fsck man page for
suggestions of what sort of information to include when submitting bug
reports for these programs.
