Same for completion queue. > > I repeat : > - slub dont touch objects in normal situations. > - LIFO is better for caches. > - LIFO is faster (one pointer for the queue head) No matter what is faster, we have to process packets in FIFO order, otherwise we get reordering within a flow which is to be absolutely avoided. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
