I see nothing in /sys/devices/virtual/workqueues (urg should be > /sys/kernel/workqueues) that shows that? Yeah you can see that with workqueue tracing events. Check out /sys/kernel/debug/tracing/events/workqueue/ and more specifically workqueue_execute_start/ and workqueue_queue_work/. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
