Subject: [PATCH 18/19] tests: add regression tests for group descriptors
 with bad checksums

From: Darrick J. Wong <darrick.wong@...cle.com>

Add tests to examine how e2fsck deals with (a) the block bitmap being
corrupt; (b) the inode bitmap being corrupt; (c) the bitmap checksums
being incorrect (but the bitmaps are fine); and (d) the group
descriptor checksum itself is incorrect.
