Subject: [GIT PULL] afs: Fix refcount handling

Hi Linus,

Could you pull this pair of patches?  The first patch converts afs to use
refcount_t for its refcounts and the second patch fixes afs_put_call() and
afs_put_server() to save the values they're going to log in the tracepoint
before decrementing the refcount.

Thanks,
David
