262 Main feature differing them of generic softirqs: tasklet is running only on one CPU simultaneously.
265 Main feature differing them of BHs: different tasklets may be run simultaneously on different CPUs.
268 Properties:
269 * If tasklet_schedule() is called, then tasklet is guaranteed to be executed on some cpu at least once after this.
271 * If the tasklet is already scheduled, but its excecution is still not
272 started, it will be executed only once.
273 * If this tasklet is already running on another CPU (or schedule is called
274 from tasklet itself), it is rescheduled for later.
275 * Tasklet is strictly serialized wrt itself, but not wrt another tasklets. If client needs some intertask synchronization, he makes it with spinlocks.
