Some quick comments: - singlethread_cpu needs to be hotplug safe (broken currently) - Any reason why cpu_populated_map is not modified on CPU_DEAD? - I feel more comfortable if workqueue_cpu_callback were to take workqueue_mutex in LOCK_ACQ and release it in LOCK_RELEASE notifications. This will provide stable access to cpu_populated_map to functions like __create_workqueue. Finally, I wonder if these changes will be unnecessary if we move to process freezer based hotplug locking ... -- Regards, vatsa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
