391  * stop_stop_kthread - Inform the hardware latency sampling/detector kthread to stop
393  * This kicks the running hardware latency sampling/detector kernel thread and
394  * tells it to stop sampling now. Use this on unload and at system shutdown.

475  * This kicks the running hardware latency sampling/detector kernel threads and
476  * tells it to stop sampling now. Use this on unload and at system shutdown.
