From f05c0daaf68e424d05d271c7fb2fbfd5750a315e Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Fri, 10 Oct 2014 16:39:05 +0400 Subject: libceph: ceph-msgr workqueue needs a resque worker 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.
