David Howells says:
====================
rxrpc: Local abort tracepoint
Here are two patches. They need to be applied on top of the just-posted
call refcount overhaul patch:
(1) Fix the return value of some call completion helpers.
(2) Add a tracepoint that allows local aborts to be debugged.
====================
