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

Pull ceph updates from Sage Weil:
 "The big item here is support for inline data for CephFS and for
  message signatures from Zheng.  There are also several bug fixes,
  including interrupted flock request handling, 0-length xattrs, mksnap,
  cached readdir results, and a message version compat field.  Finally
  there are several cleanups from Ilya, Dan, and Markus.

  Note that there is another series coming soon that fixes some bugs in
  the RBD 'lingering' requests, but it isn't quite ready yet"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: (27 commits)
