Hi Trond,
I'm trying to get to the bottom of a backchannel problem, but with
tracepoints enabled things blow up in trace_rpc_task_sleep() because there's
no rpc_clnt (or easy way to get to one) on a backchannel request.
The only reason we're sending the rpc_clnt to that tracepoint is to emit the
cl_clid:

SUNRPC: Add an identifier for struct rpc_clnt
Add an identifier in order to aid debugging.
Can we rather just use the address of the struct rpc_clnt rather than an
integer in the tracepoint?
Alternatively, I can try to figure out how to have each backchannel request
have a reference to the rpc_clnt, or perhaps make the call to the tracepoint
conditional.
