[SOCK]: Add some notes about per-bind-bucket sock lookup.
I was asked about "why don't we perform a sk_net filtering in bind_conflict calls, like we do in other sock lookup places" for a couple of times. Can we please add a comment about why we do not need one? Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
