So no difference from using the sysfs interface or doing it on the box side, doesn't work either way. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
