I know this is maybe stupid, but... At the beggining of sched.c, this commentary appears: /* * 'sched.c' is the main kernel file. It contains scheduling primitives * (sleep_on, wakeup, schedule etc) as well as a number of simple system * call functions (type getpid()), which just extract a field from * current-task */ Shouldn't be ommited the last part ? It has several system calls, but sys_getpid is in timer.c, not in sched.c.
