Perhaps we could have a single cpu hotplug notifier in the percpu_counter library. Add register/deregister functions to the percpu_counter API so that all percpu_counters in the machine can be linked together. One _could_ just register and deregister the counters in percpu_counter_init() and percpu_counter_destroy(), but perhaps that wouldn't suit all callers, dunno. - 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/
