CPU0 CPU1 work_queue(a) work_queue(a) -> work_cancel(a) -> work_cancel(a) -> enter_critical() -> sq_addlast(a) -> leave_critical() -> enter_critical() -> sq_addlast(a) // double add, wrong -> leave_critical() Also, this happens in mulit-threads in one CPU. Fix: work_cancel() should in critical section. Signed-off-by: ligd <liguiding1@xiaomi.com> |
