Date: Sun, 12 Jan 2014 15:54:30 +0800 From: Weiping Pan <panweiping3@...il.com> To: netdev@...r.kernel.org Subject: [PATCH net 1/2] tcp: delete redundant calls of tcp_mtup_init() As both tcp_v4_syn_recv_sock() and tcp_v6_syn_recv_sock() already call tcp_mtup_init() for new sock, the calls of it in tcp_rcv_state_process() and tcp_v4_conn_req_fastopen() are redundant.
