[IPV4]: INET_MATCH() annotations
INET_MATCH() and friends depend on an interesting set of kludges: * there's a pair of adjacent fields in struct inet_sock - __be16 dport followed by __u16 num. We want to search by pair, so we combine the keys into a single 32bit value and compare with 32bit value read from &...->dport. * on 64bit targets we combine comparisons with pair of adjacent __be32 fields in the same way. Make sure that we don't mix those values with anything else and that pairs we form them from have correct types. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S.
