Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org This makes that ip6_route_net_init() does all of the route init code. There used to be a race between ip6_route_net_init() and ip6_net_init() and someone relying on the combined result was left out cold.
