Hmm, I wouldn't be so sure about this particular advice. With PREEMPT_RT, interrupt handlers are force-threaded and run in process context, therefore with hardirqs enabled. This driver doesn't call request_irq with IRQF_NO_THREAD, so calling napi_schedule_irqoff would create a bug that is very, very difficult to find. Thanks, -Vladimir
