    Linus Torvalds authored
    Pull Ceph updates from Sage Weil:
     "A few groups of patches here.  Alex has been hard at work improving
      the RBD code, layout groundwork for understanding the new formats and
      doing layering.  Most of the infrastructure is now in place for the
      final bits that will come with the next window.
      There are a few changes to the data layout.  Jim Schutt's patch fixes
      some non-ideal CRUSH behavior, and a set of patches from me updates
      the client to speak a newer version of the protocol and implement an
      improved hashing strategy across storage nodes (when the server side
      supports it too).
      A pair of patches from Sam Lang fix the atomicity of open+create
      operations.  Several patches from Yan, Zheng fix various mds/client
      issues that turned up during multi-mds torture tests.
      A final set of patches expose file layouts via virtual xattrs, and
      allow the policies to be set on directories via xattrs as well
      (avoiding the awkward ioctl interface and providing a consistent
      interface for both kernel mount and ceph-fuse users)."
