commit a057b2332f5780b71018630f18f2619480118c5d
Author: Theodore Ts'o <tytso@xxxxxxx>
Date: Sun Nov 16 10:03:00 2008 -0500
Fix various signed/unsigned gcc warnings
Some of these could affect filesystems between 2^31 and 2^32-1 blocks.
Thanks to Valerie Aurora Henson for pointing out the problems in
lib/ext2fs/alloc_tables.c, which led me to do a "make gcc-wall"
scan over the source tree.
