Thank you for the example. I understand what are the scheduling mechanics depending on task->state. But suppose another situation. Let's say I change current state to TASK_INTERRUPTIBLE. If I start now some long operation, then shouldn't the scheduler kick in as soon as he can and put my thread asleep? Or should I call necessarily schedule()? And if so, why? _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
