    [IPV4]: INET_MATCH() annotations · 4f765d84

    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.
