Subject: [PATCH 19/19] tests: add regression tests for inodes with bad
checksums
From: Darrick J. Wong <darrick.wong@...cle.com>
Add regression tests to e2fsck to examine how it deals with inode
table blocks which (a) have been zero'd; (b) have been one'd; (c) have
corrupt inodes with obvious problems; and (d) have inodes with
non-obvious problems.
