> 
> The big patch at the end of the series overhauls how rxrpc_call refcounting
> is handled, making it more sane so that calls bound to user IDs are _only_
> released from socket operations or kernel API functions.  Further, the
> patch stops calls from holding refs on their parent socket - which can
> prevent the socket from being cleaned up.
> 
> The second largest patch improves the call tracking tracepoint by providing
> extra information about the situation in which gets and puts occur.  This
> allows distinctions to be drawn between refs held by the socket user ID
> tree, refs held by the work queue (to be implemented by a future patch) and
> other refs.
> 
> The other patches include a couple of cleanups and some simple alterations
> to avoid NULL pointer dereferences in the big patch.
