Pull Ceph updates from Sage Weil:
 "This has a mix of bug fixes and cleanups.

  Alex's patch fixes a rare race in RBD.  Ilya's patches fix an ENOENT
  check when a second rbd image is mapped and a couple memory leaks.
  Zheng fixes several issues with fragmented directories and multiple
  MDSs.  Josh fixes a spin/sleep issue, and Josh and Guangliang's
  patches fix setting and unsetting RBD images read-only.

  Naturally there are several other cleanups mixed in for good measure"
