CONFIG_SCHEDSTATS: Collect scheduler statistics

收集调度信息

​ If you say Y here, additional code will be inserted into the scheduler and related routines to collect statistics about scheduler behavior and provide them in /proc/schedstat. These stats may be useful for both tuning and debugging the scheduler 。If you aren't debugging the scheduler or trying to tune a specific application, you can say N to avoid the very slight overhead this adds.
