Subject: [PATCH 3/4] xfs_mdrestore: recalculate sb CRC before writing
Date: Mon, 27 May 2013 17:14:55 +1000 [thread overview]
Message-ID: <1369638896-24872-4-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1369638896-24872-1-git-send-email-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
xfs_mdrestore writes the superblock after modifying it, and so the
CRC is not necessarily correct. make sure the CRC is correct
before we write the superblock back.
