Is CONFIG_NET intentional?
yes. it is config_net for now, until eBPF is completely separate from net. Then it will gain its own config_bpf, so it can be used in net-less setups or disabled in net-full setups by folks who care about last byte of .text size. Future will tell. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
