    Subject[PATCH 3.10 123/123] libceph: ceph-msgr workqueue needs a resque worker
    Date
    3.10-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Ilya Dryomov <idryomov@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.
