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.
David --- The following changes since commit f16180739cd18a39a1a45516ac0e65d18a9f100e:
Merge remote-tracking branch 'net/master' into afs-next (2019-09-02 11:43:44 +0100)
