Subject: [PATCH 4.2.y-ckt 121/206] xfs: skip stale inodes in xfs_iflush_cluster

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

From: Dave Chinner <dchinner@...hat.com>

commit 7d3aa7fe970791f1a674b14572a411accf2f4d4e upstream.

We don't write back stale inodes so we should skip them in
xfs_iflush_cluster, too.
