Registering Tasklets

tasklet_schedule registers a tasklet in the system:


static inline void tasklet_schedule(struct tasklet_struct *t);

If the tasklet_state_sched bit is set, registration is terminated because the tasklet is already registered. Otherwise, the tasklet is placed at the start of a list whose list header is the CPU-specific variable tasklet_vec. This list contains all registered tasklets and uses the next element for linking purposes.

The tasklet list is marked for processing once a tasklet has been registered.
