From 7bc3074c27bb1eae7c8ccacd920ba55454381786 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 13 Oct 2015 12:39:59 +0200 Subject: [PATCH] net/dump: Rework net-dump init functions Move the creation of the dump client from net_dump_init() into net_init_dump(), so we can later use the former function for dump via netfilter, too. Also rename net_dump_init() to net_dump_state_init() to make it easier distinguishable from net_init_dump().
