Subject: [BUG RT] WARNING: at kernel/sched.c:5071 2.6.23-rc1-rt7

Ingo,

The below ifndef, shouldn't that be ifndef CONFIG_PREEMPT_SOFTIRQS ?
I hit that warning while I was running !PREEMPT_RT but with both hard
and softiqs as threads.


int __sched cond_resched_softirq(void)
{
#ifndef CONFIG_PREEMPT_RT
	WARN_ON_ONCE(!in_softirq());
#endif
	if (need_resched() && system_state == SYSTEM_RUNNING) {
		local_bh_enable();
		__cond_resched();
		local_bh_disable();
		return 1;
	}
	return 0;
}


-- Steve

P.S. I really found out that the system becomes VERY non-responsive when
you run with both hard and softirqs as threads, but with
PREEMPT_NONE ;-)
