10:03 <baotiao> how can I use systemtap to print stack variable in some function

10:05 <baotiao> I have try use probe kernel.function("*@kernel/sched.c:686"){ printf("Active process: %d\n", $array->nr_active) } but it always return that no match function

11:53 <fche> baotiao, you're on the right track; that should work if you have debuginfo and your function's accessible to a debugger such as stap

11:53 <fche> try stap -L 'kernel.function("*@kernel/sched.c:686")' <--- is that a function or a statement btw ?
