Subject: [PATCH 4.5 107/128] xfs: skip stale inodes in xfs_iflush_cluster

4.5-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.
