From 6065e1395e52b971a1dc96dece9011a236371824 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Peter=20Pan=28=E6=BD=98=E5=8D=AB=E5=B9=B3=29?= <panweiping3@gmail.com> Date: Sun, 19 Jan 2014 20:44:46 +0800 Subject: [PATCH] tcp: delete redundant calls of tcp_mtup_init() As tcp_rcv_state_process() has already calls tcp_mtup_init() for non-fastopen sock, we can delete the redundant calls of tcp_mtup_init() in tcp_{v4,v6}_syn_recv_sock().
