27 * sampling the built-in CPU timer, looking for discontiguous readings.
109 u64 sample_window; /* total sampling window (on+off) */
110 u64 sample_width; /* active sampling portion of window */
349 * kthread_fn - The CPU time sampling/hardware latency detection kernel thread
389 * stop_stop_kthread - Inform the hardware latency sampling/detector kthread to stop
391 * This kicks the running hardware latency sampling/detector kernel thread and
392 * tells it to stop sampling now. Use this on unload and at system shutdown.
414 * start_single_kthread - Kick off the hardware latency sampling/detector kthread

471 * stop_per_cpu_kthreads - Inform the hardware latency sampling/detector kthread to stop
473 * This kicks the running hardware latency sampling/detector kernel threads and
474 * tells it to stop sampling now. Use this on unload and at system shutdown.
