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

Pull Ceph updates from Sage Weil:
 "There is some follow-on RBD cleanup after the last window's code drop,
  a series from Yan fixing multi-mds behavior in cephfs, and then a
  sprinkling of bug fixes all around.  Some warnings, sleeping while
  atomic, a null dereference, and cleanups"
