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 ;-)
