Subject: [PATCH 3/6] xfs: skip stale inodes in xfs_iflush_cluster
Date: Fri, 8 Apr 2016 09:37:48 +1000 [thread overview]
Message-ID: <1460072271-23923-4-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1460072271-23923-1-git-send-email-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
We don't write back stale inodes so we should skip them in
xfs_iflush_cluster, too.
