From a379854d91b2cb0af07b0f62845449f4dacbd673 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Tue, 15 Nov 2016 21:36:39 +0100 Subject: [PATCH] netfilter: conntrack: remove unused init_net hook since adf0516845bcd0 ("netfilter: remove ip_conntrack* sysctl compat code") the only user (ipv4 tracker) sets this to an empty stub function. After this change nf_ct_l3proto_pernet_register() is also empty, but this will change in a followup patch to add conditional register of the hooks.
