    tcp: Get rid of inetpeer special cases. · 4670fd81
    David S. Miller 提交于
    The get_peer method TCP uses is full of special cases that make no
    sense accommodating, and it also gets in the way of doing more
    reasonable things here.
    
    First of all, if the socket doesn't have a usable cached route, there
    is no sense in trying to optimize timewait recycling.
    
    Likewise for the case where we have IP options, such as SRR enabled,
    that make the IP header destination address (and thus the destination
    address of the route key) differ from that of the connection's
    destination address.
    
    Just return a NULL peer in these cases, and thus we're also able to
    get rid of the clumsy inetpeer release logic.
