From b9e2e689aab293c3da0ceac0921449a07b692f1f Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 17 Jan 2019 11:23:36 -0800 Subject: tcp: move mdev_us init to tcp_disconnect() If we make sure a listener always has its mdev_us 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.
