In addition to thawing worker thread before kthread_stopping it, there are minor changes required in worker threads, to check for is_cpu_offline(bind_cpu) when they come out of refrigerator and jump to wait_to_die if so (ex: softirq.c). I guess you would need these changes before freezer-based hotplug is merged, in which case Gautham can send those patches out first. -- 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/
