Darrick J. Wong 538ef36326 resize2fs: don't play stupid games with the block count
While it may be true that playing games with old_fs' block count
during a grow operation shuts up a bunch of warnings, resize2fs
doesn't actually expand the group descriptor array to match the size
we're artificially stuffing into old_fs, which means that if we
actually need to allocate a block out of the larger fs (i.e. we're in
desperation mode), ext2fs_block_alloc_stats2() scribbles on the heap,
leading to crashes if you're lucky and FS corruption if not.

So, rip that piece out and turn off com_err warnings properly and add
a test case to deal with growing a nearly full filesystem.

README

	This is the new version (1.42.12) 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.
