Subject: [PATCH 10/27] e2fsck: fix infinite loop when recovering corrupt journal blocks
Date: Sat, 16 Aug 2014 16:46:55 -0700 [thread overview]
Message-ID: <20140816234655.11171.49022.stgit@birch.djwong.org> (raw)
In-Reply-To: <20140816234550.11171.61585.stgit@birch.djwong.org>
When recovering the journal, don't fall into an infinite loop if we
encounter a corrupt journal block. Instead, just skip the block and
proceed with the full filesystem fsck.
The test case for this will be "j_corrupt_journal_block" further on
in the patch series.
