Subject: [PATCH 18/55] xfs: scrub AGF and AGFL
Date: Sat, 21 Jan 2017 00:02:09 -0800 [thread overview]
Message-ID: <148498572958.15323.12962471162017853379.stgit@birch.djwong.org> (raw)
In-Reply-To: <148498561504.15323.8531512066874274553.stgit@birch.djwong.org>
Check the block references in the AGF and AGFL headers to make sure
they make sense.
