So something like following is allowed? preempt_disable(); udelay(5); preempt_enable(); ????? I must admit, this is a shock to me.
Hmmm even I think this is not possible, because these functions call the schedule() function, which should not be done in atomic context. It does a check for in_atomic() which checks the preempt_counter().
