likely()/unlikely() are not always applicable. In the Ipv6 case I mentioned to you, it all depends if an application for some reason absolutely wants the sockets to store the extra skb There are seldom used socket options. _if_/_when_ they are used, a likely()/unlikely() would give the wrong signal. likely() should only be used in contexts we know better than branch predictor/compiler. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
