Tasklets are scheduled through the softirq mechanism, sometimes through ksoftirqd (a per-CPU kernel thread), when the machine is under heavy soft-interrupt load.
通过软中断机制来调度微线程,当机器处于严重软件中断负荷之下时, 可通过 ksoftirqd(一种每 CPU 内核线程)软中断来调度。

Finally, the mechanism and the implementation of softinterrupt are introduced.
