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

Pull Ceph fixes from Sage Weil:
 "There is a lifecycle fix in the auth code, a fix for a narrow race
  condition on map, and a helpful message in the log when there is a
  feature mismatch (which happens frequently now that the default
  server-side options have changed)"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
  rbd: report unsupported features to syslog
  rbd: fix rbd map vs notify races
  libceph: make authorizer destruction independent of ceph_auth_client
