    Pull ceph updates from Ilya Dryomov:
     "Lots of exciting things this time!
    
       - support for rbd object-map and fast-diff features (myself). This
         will speed up reads, discards and things like snap diffs on sparse
         images.
    
       - ceph.snap.btime vxattr to expose snapshot creation time (David
         Disseldorp). This will be used to integrate with "Restore Previous
         Versions" feature added in Windows 7 for folks who reexport ceph
         through SMB.
    
       - security xattrs for ceph (Zheng Yan). Only selinux is supported for
         now due to the limitations of ->dentry_init_security().
    
       - support for MSG_ADDR2, FS_BTIME and FS_CHANGE_ATTR features (Jeff
         Layton). This is actually a single feature bit which was missing
         because of the filesystem pieces. With this in, the kernel client
         will finally be reported as "luminous" by "ceph features" -- it is
         still being reported as "jewel" even though all required Luminous
         features were implemented in 4.13.
    
       - stop NULL-terminating ceph vxattrs (Jeff Layton). The convention
         with xattrs is to not terminate and this was causing
         inconsistencies with ceph-fuse.
    
       - change filesystem time granularity from 1 us to 1 ns, again fixing
         an inconsistency with ceph-fuse (Luis Henriques).
    
      On top of this there are some additional dentry name handling and cap
      flushing fixes from Zheng. Finally, Jeff is formally taking over for
      Zheng as the filesystem maintainer"
