Using a "normal" 2.6.34 kernel I get the following errors: $ sudo ./run-stap -wp4 testsuite/buildok/rpc-all-probes.stp semantic error: no match while resolving probe point module("sunrpc").function("rpc_new_client").return semantic error: no match while resolving probe point sunrpc.clnt.create_client.return semantic error: no match while resolving probe point module("sunrpc").function("rpc_release_task").return semantic error: no match while resolving probe point sunrpc.sched.release_task.return Pass 2: analysis failed. Try again with another '--vp 01' option. Now when I use a 2.6.34 kernel compiled with the '-fno-inline-functions-called-once' flag (which turns off inline-ing when routines are called from only one place) the run-tap does not fail. And sure enough, both rpc_new_client() and rpc_release_task() are only called from one place. So is there a work-around for this or should I just post the minor changes I have and move on? steved.
