Hi All ! As we know, every CPU has a tasklet list, all these heads are stored in tasklet_vec[NRCPUS]. A tasklet may have one of the two states:TASKLET_STATE_SCHED and TASKLET_STATE_RUN. TASKLET_STATE_SCHED makes that a tasklet can only be linked on one of these lists. TASKLET_STATE_RUN makes that tasklet_action() do nothing when the tasklet is running on the other CPU. My question is when does this happen: a running tasklet is scheduled on the other CPU ? -- Kernelnewbies: Help each other learn about the Linux kernel.
