3.16.7-ckt2 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Ilya Dryomov <idryo...@redhat.com> commit f9865f06f7f18c6661c88d0511f05c48612319cc upstream. Commit f363e45fd118 ("net/ceph: make ceph_msgr_wq non-reentrant") effectively removed WQ_MEM_RECLAIM flag from ceph_msgr_wq. This is wrong - libceph is very much a memory reclaim path, so restore it.
