Hi Linus,
Here's a set of patches for AFS. The first three are trivial, deleting
unused symbols and rolling out a wrapper function.
The fourth and fifth patches make use of the previously added RCU-safe
request_key facility to allow afs_permission() and afs_d_revalidate() to
attempt to operate without dropping out of RCU-mode pathwalk. Under
certain conditions, such as conflict with another client, we still have to
drop out anyway, take a lock and consult the server.
