Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client

Pull ceph revert from Sage Weil:
 "This corrects a recent misadventure with __GFP_MEMALLOC and
  PF_MEMALLOC; it turns out it's not a good fit for RBD and we're better
  off relying on dirty page throttling"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
  Revert "libceph: use memalloc flags for net IO"
