From 91950833dd5a34ac6336aa88da6d43aaeb56ac6d Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Sat, 12 Aug 2017 00:57:06 +0200 Subject: netfilter: conntrack: place print_tuple in procfs part CONFIG_NF_CONNTRACK_PROCFS is deprecated, no need to use a function pointer in the trackers for this. Place the printf formatting in the one place that uses it.
