Softirqs and tasklets are strictly correlated, because tasklets are implemented on top of softirqs. As a matter of fact, the term "softirq", which appears in the kernel source code, often denotes both kinds of deferrable functions. Another widely used term isinterrupt context:it specifies that ...

To activate the tasklet, you should invoke either the tasklet_schedule( ) function or the tasklet_hi_schedule( ) function, according to the priority that you require for the tasklet. The two functions are very similar; each of them performs the following actions: Checks the TASKLET_STATE_SCHED...
