These changes provide a fully preemptible kernel, threaded interrupt handlers, high-resolution timers, priority inheritance, and robust mutexes.

这些更改提供了完全抢占式内核、线程中断处理程序、高分辨率计时器、优先级继承和健壮的互斥锁（mutex）。

The system is fully preemptible when this function is called. The kernel does no processing, but it passes all parameters directly to the function supplied by you.

当这个函数被调用的时候系统完全可能被抢占，内核没有处理，直接传递参数到你提供的函数。
