[PATCH 0/3] libceph, rbd: don't lockup under memory pressure

Ilya Dryomov <ilya.dryomov@xxxxxxxxxxx> · Fri, 10 Oct 2014 22:27:03 +0400

Hello,

These are fixes for the problem that Micha was running into and helped
debug.  It appeared to be a stupid bug in messenger and to a lesser
extent in rbd - workqueues in memory reclaim paths really do need to
have WQ_MEM_RECLAIM set.

Thanks,

                Ilya

  libceph: ceph-msgr workqueue needs a resque worker
  rbd: rbd workqueues need a resque worker
  rbd: use a single workqueue for all devices
