Subject: [PATCH 13/19] tests: add regression tests for EA blocks with bad
 checksums

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

Add regression tests for e2fsck dealing with (a) EA block with a bad
checksum; (b) EA block with a bad magic number; and (c) EA block with
damage that isn't otherwise noticeable.
