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

Pull Ceph updates from Sage Weil:
 "There are several patches from Ilya fixing RBD allocation lifecycle
  issues, a series adding a nocephx_sign_messages option (and associated
  bug fixes/cleanups), several patches from Zheng improving the
  (directory) fsync behavior, a big improvement in IO for direct-io
  requests when striping is enabled from Caifeng, and several other
  small fixes and cleanups"
