Dear mentors, After tired digging, I'm wholly stuck in tasklet_kill(). Hope your help. >From the source tree (4.9.168), I got: 1. TASKLET_STATE_SCHED flag is only set by tasklet_schedule(). (also in dccp_tasklet_schedule()). 2. tasklet_schedule() immediately put the tasklet to queue tasklet_vec. 3. softirq handler tasklet_action() run the queue and clear their SCHED flag. 4. Unlike tasklet_kill_immediate, tasklet_kill() doesn't touch tasklet_vec. 5. tasklet_kill() just yield to waiting the tasklet complete and clear its SCHED flag. Then how to say the tasklet been killed? If a tasklet SCHED flag been set, it must be in tasklet_vec queue. At this time, tasklet_kill does not kick it out of the queue but waiting it to run over. Is my understanding right or I miss something? Thanks, laokz _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
