Subject: [PATCH 5.4 110/120] xfs: convert EIO to EFSCORRUPTED when log contents are invalid

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

commit 895e196fb6f84402dcd0c1d3c3feb8a58049564e upstream.

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