Pull afs fixes from David Howells:

 - Fix the CB.ProbeUuid handler to generate its reply correctly.

 - Fix a mix up in indices when parsing a Volume Location entry record.

 - Fix a potential NULL-pointer deref when cleaning up a read request.

 - Fix the expected data version of the destination directory in

 - Fix afs_d_revalidate() to only update d_fsdata if it's not the same
   as the directory data version to reduce the likelihood of overwriting
   the result of a competing operation. (d_fsdata carries the directory
   DV or the least-significant word thereof).

 - Fix the tracking of the data-version on a directory and make sure
   that dentry objects get properly initialised, updated and

   Also fix rename to update d_fsdata to match the new directory's DV if
   the dentry gets moved over and unhash the dentry to stop
   afs_d_revalidate() from interfering.
