The unit mentioned in the documentation of scheduler statistics is outdated which may mislead the readers. The unit of statistics that is reported by /proc/schedstat is modified to nanosecond, and the unit of statistics that is reported by /proc/PID/schedstat is provided as well to make the context consistent. The rq_cpu_time and the rq_sched_info.run_delay of a run queue, and the sched_info.run_delay of a task are all updated based on the clock of the run queue, while the se.sum_exec_runtime of a task is updated based on the clock_task of the run queue of the task. Both the clock and clock_task are relied on the return value of the function sched_clock() which is in the unit of nanosecond.
