  "message": "[INET]: Generalise tcp_tw_bucket, aka TIME_WAIT sockets\n\nThis paves the way to generalise the rest of the sock ID lookup\nroutines and saves some bytes in TCPv4 TIME_WAIT sockets on distro\nkernels (where IPv6 is always built as a module):\n\n[root@qemu ~]# grep tw_sock /proc/slabinfo\ntw_sock_TCPv6  0  0  128  31  1\ntw_sock_TCP    0  0   96  41  1\n[root@qemu ~]#\n\nNow if a protocol wants to use the TIME_WAIT generic infrastructure it\nonly has to set the sk_prot-\u003etwsk_obj_size field with the size of its\ninet_timewait_sock derived sock and proto_register will create\nsk_prot-\u003etwsk_slab, for now its only for INET sockets, but we can\nintroduce timewait_sock later if some non INET transport protocolo\nwants to use this stuff.\n\nNext changesets will take advantage of this new infrastructure to\ngeneralise even more TCP code.\n\n[acme@toy net-2.6.14]$ grep built-in /tmp/before.size /tmp/after.size\n/tmp/before.size: 188646   11764    5068  205478   322a6 net/ipv4/built-in.o\n/tmp/after.size:  188144   11764    5068  204976   320b0 net/ipv4/built-in.o\n[acme@toy net-2.6.14]$\n\nTested with both IPv4 \u0026 IPv6 (::1 (localhost) \u0026 ::ffff:172.20.0.1\n(qemu host)).\n\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@ghostprotocols.net\u003e\nSigned-off-by: David S.
