  SUNRPC: Micro-optimize __rpc_execute (2018-01-23 09:44:40 -0500)

----------------------------------------------------------------
These patches include a handful of bugfixes and cleanups in addition to adding
tracepoints to xprtrdma.  There are also a few generic sunrpc tracepoint fixes
tagged on at the end to keep the display format consistent.

Thanks,
Anna
