Subject: [PATCH 4/4] xfs: convert EIO to EFSCORRUPTED when log contents are invalid
Date: Wed, 06 Nov 2019 19:02:15 -0800	[thread overview]
Message-ID: <157309573590.45542.17137773028975239453.stgit@magnolia> (raw)
In-Reply-To: <157309570855.45542.14663613458519550414.stgit@magnolia>

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

Convert EIO to EFSCORRUPTED in the logging code when we can determine
that the log contents are invalid.
