Block very much optimizes for the cases of either 1 queue or enough queues for all cpus at the moments. It would be good to check what the network drivers currently do. -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
