[PATCH net-next 0/8] rxrpc: Preparation for removal of use of skbs from AFS

[David Howells <dhowells@redhat.com>]

Here's a set of patches that prepare the way for the removal of the use of
sk_buffs from fs/afs (they'll be entirely retained within net/rxrpc):

 (1) Fix a potential NULL-pointer deref in rxrpc_abort_calls().

 (2) Condense all the terminal call state machine states to a single one
     plus supplementary info.

 (3) Add a trace point for rxrpc call usage debugging.

 (4) Cleanups and missing headers.

 (5) Provide a way for AFS to ask about a call's peer address without
     having an sk_buff to query.

 (6) Use call->peer directly rather than going via call->conn (which might
     be NULL).

 (7) Pass struct socket * to various rxrpc kernel interface functions so
     they can use that directly rather than getting it from the rxrpc_call
     struct.

The patches can be found here also (non-terminally on the branch):
