Subject: [PATCH net 0/6] rxrpc: Fixes

Here is a collection of fixes for rxrpc:

 (1) rxrpc_error_report() needs to call sock_error() to clear the error
     code from the UDP transport socket, lest it be unexpectedly revisited
     on the next kernel_sendmsg() call.  This has been causing all sorts of
     weird effects in AFS as the effects have typically been felt by the
     wrong RxRPC call.

 (2) Allow a kernel user of AF_RXRPC to easily detect if an rxrpc call has

 (3) Allow errors incurred by attempting to transmit data through the UDP
     socket to get back up the stack to AFS.

 (4) Make AFS use (2) to abort the synchronous-mode call waiting loop if
     the rxrpc-level call completed.

 (5) Add a missing tracepoint case for tracing abort reception.

 (6) Fix detection and handling of out-of-order ACKs.
