Hmm, this code is a bit odd, because it will cause an error
if both probe points do not exist.
I think this should use "never" and "!" like below.

probe sunrpc.sched.release_task.return =
kernel.function("rpc_release_task").return !,
module("sunrpc").function("rpc_release_task").return !,
never {...
