The subroutines that ran in the kernel code are idled (the process that is run when the CPU is idle) and schedule (the kernel scheduler).

内核代码中子例程是 idled （当 CPU 空闲时运行的进程）和 schedule（内核调度器）。

The CPU usage thus gathered is used by the kernel, which may schedule or de-schedule a process based on its priority, current CPU usage, and CPU limits.

内核使用收集的 CPU 使用量数据，可以根据优先级、当前 CPU 使用量和 CPU 限制调度或撤消运行进程。
