[INET]: Change protocol field in struct inet_protosw to u16
[acme@newtoy net-2.6.20]$ pahole /tmp/tcp_ipv6.o inet_protosw /* /pub/scm/linux/kernel/git/acme/net-2.6.20/include/net/protocol.h:69 */ struct inet_protosw { struct list_head list; /* 0 8 */ short unsigned int type; /* 8 2 */ /* XXX 2 bytes hole, try to pack */ int protocol; /* 12 4 */ struct proto * prot; /* 16 4 */ const struct proto_ops * ops; /* 20 4 */ int capability; /* 24 4 */ char no_check; /* 28 1 */ unsigned char flags; /* 29 1 */ }; /* size: 32, sum members: 28, holes: 1, sum holes: 2, padding: 2 */ So that we can kill that hole, protocol can only go all the way to 255 (RAW).
