Subject: [PATCH 07/24] xfs: scrub AGF and AGFL
Date: Thu, 25 Aug 2016 16:56:03 -0700	[thread overview]
Message-ID: <147216936304.6398.907217110911507233.stgit@birch.djwong.org> (raw)
In-Reply-To: <147216931783.6398.1716678878794493264.stgit@birch.djwong.org>

Check the block references in the AGF and AGFL headers to make sure
they make sense.
