Theodore Ts'o 3aa8f60aae libext2fs: fix uninit block calculation when inodes_per_block < first_ino 
The following commands:

	dd if=/dev/zero of=/tmp/foo count=1 ibs=$(( 256 * 1024 * 1024 ))
	mke2fs -N 256 -t ext4 /tmp/foo

... will cause mke2fs to write until it fills the device.  The cause
for this is that the explicit request for 256 inodes causes the number
of inodes per block group to be 8.  The ext2fs_initialize() function
assumed that all of the reserved inodes would be in the first block
group, which is not true in this case.  This caused the number of
uninitialized inodes in the first block group to be negative, which
then resulted in mke2fs trying to zero out a very large number of
blocks.  Oops.

README 

	This is the new version (1.42.4) 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.
