From 639e077b43d9c54ffb1e1b54a2de54597ceae1d8 Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Mon, 7 Dec 2015 12:13:26 +0200 Subject: [PATCH] netfilter: nfnetlink_queue: Unregister pernet subsys in case of init failure Commit 3bfe049807c2403 ("netfilter: nfnetlink_{log,queue}: Register pernet in first place") reorganised the initialisation order of the pernet_subsys to avoid "use-before-initialised" condition. However, in doing so the cleanup logic in nfnetlink_queue got botched in that the pernet_subsys wasn't cleaned in case nfnetlink_subsys_register failed. This patch adds the necessary cleanup routine call.
