Subject[GIT PULL] afs: Fixes
Hi Linus,

Can you pull these afs fixes please?

(1) Fix the CB.ProbeUuid handler to generate its reply correctly.

(2) Fix a mix up in indices when parsing a Volume Location entry record.

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

(4) Fix the expected data version of the destination directory in

(5) 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).

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

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.

The following changes since commit 2a11c76e5301dddefcb618dac04f74e6314df6bc:
