Very useful for debugging. Yes, but many sleeping/scheduling (such as schedule_timeout(), __down(), etc.) are compiled without -fno-omit-frame-pointer, so you can not find the caller of such functions anyway. And some sleeping/scheduling functions which are compiled with -fno-omit-frame-pointer are static or deprecated (sleep_on(), etc.) You can find the caller of "schedule()" even with simple thread_saved_pc(). I think it is enough so I do not think it is worth to fix (and maintain) current minfo[]. --- Atsushi Nemoto
