From 9c7a4f9ce651383c73dfdff3d7e21d5f9572c4ec Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Tue, 22 Mar 2011 19:17:36 -0700 Subject: [PATCH] ipv6: ip6_route_output does not modify sk parameter, so make it const This avoids explicit cast to avoid 'discards qualifiers' compiler warning in a netfilter patch that i've been working on.
