From: Peter Pan(潘卫平) Date: Sun, 19 Jan 2014 12:44:46 +0000 (+0800) Subject: tcp: delete redundant calls of tcp_mtup_init() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4d83e1773031c2b7bbcfeb3736ad20980785dd93;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git 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().
