Hi,
This comment is written in head of reschedule_idle, is it really
correct?
--------------------------
/*
* This is ugly, but reschedule_idle() is very timing-critical.
* We enter with the runqueue spinlock held, but we might end
* up unlocking it early, so the caller must not unlock the
* runqueue, it's always done by reschedule_idle().
*
* This function must be inline as anything that saves and restores
* flags has to do so within the same register window on sparc (Anton)
*/
static FASTCALL(void reschedule_idle(struct task_struct * p));
static void reschedule_idle(struct task_struct * p)
--------------------------
If it is then, wake_up_process and schedule_tail are wrong.
But I think not...
--------------------------
reschedule_idle(p);
out:
spin_unlock_irqrestore(&runqueue_lock, flags);
--------------------------
