[Bug tapsets/5510] New: no match while resolving probe point sunrpc.sched.release_task.return


On RHEL5.1, I test systemtap(20071215 version) with
buildok/rpc-all-probes.stp, it reports that:
Pass 1: parsed user script and 38 library script(s) in 306usr/5sys/310real ms.
semantic error: no match while resolving probe point
sunrpc.sched.release_task.return

     I think that this is caused by that sunrpc.sched.release_task.return is not
necessarily exist. As you can see:
probe sunrpc.sched.release_task.return =
kernel.function("rpc_release_task").return ?,
module("sunrpc").function("rpc_release_task").return ?
{
name = "sunrpc.sched.release_task.return"
} 

     So I want to change it as follwowing:
--- /home/baiwd/stapsrc/src/tapset/rpc.stp 2007-11-08 11:02:47.000000000 +0900
+++ ./rpc.stp 2007-12-18 18:39:44.000000000 +0900
@@ -724,7 +724,7 @@ probe sunrpc.sched.entry =

probe sunrpc.sched.return =
sunrpc.sched.new_task.return,
- sunrpc.sched.release_task.return,
+ sunrpc.sched.release_task.return ?,
sunrpc.sched.execute.return,
sunrpc.sched.delay.return
{} 

    Is this fix right?
