From 6a408147eac4a7e51ead1bcf939a71b64c2daadf Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 17 Jan 2019 11:23:33 -0800 Subject: [PATCH] tcp: move icsk_rto init to tcp_disconnect() If we make sure a listener always has its icsk_rto field set to TCP_TIMEOUT_INIT, we do not need to rewrite this field after a new clone is created. tcp_disconnect() is very seldom used in real applications.
