I do not agree with the approach of these two patches.

It is better to have tcp_rcv_state_process() (one location) make these
calls rather than each and every inet sock operations instance.

Therefore you should remove the calls from tcp_v{4,6}_recv_sock() and
keep the one in tcp_rcv_state_process().

Thanks.
