From 6f9c961546699ff8bc5e1c1c52200616867ec68a Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 25 Sep 2015 07:39:10 -0700 Subject: inet: constify ip_route_output_flow() socket argument Very soon, TCP stack might call inet_csk_route_req(), which calls inet_csk_route_req() with an unlocked listener socket, so we need to make sure ip_route_output_flow() is not trying to change any field from its socket argument.
