Subject: [PATCH 2/5] xfs: skip stale inodes in xfs_iflush_cluster
Date: Wed,  6 Apr 2016 19:22:51 +1000	[thread overview]
Message-ID: <1459934574-25543-3-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1459934574-25543-1-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.
