Pull orangefs updates from Mike Marshall:
 "Fix:

   - stop setting atime on inode dirty (Martin Brandenburg)

  Cleanups:

   - remove initialization of i_version (Jeff Layton)

   - use ARRAY_SIZE (Jérémy Lefaure)

   - call op_release sooner when creating inodes (Mike MarshallMartin
     Brandenburg)"
