Subject: [NETFILTER 08/10]: nfnetlink_log: fix module reference counting
Date: Sun,  4 Mar 2007 21:20:08 +0100 (MET)	[thread overview]
Message-ID: <20070304201916.28582.84106.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20070304201906.28582.51903.sendpatchset@localhost.localdomain>

[NETFILTER]: nfnetlink_log: fix module reference counting

Count module references correctly: after instance_destroy() there
might be timer pending and holding a reference for this netlink instance.

Based on patch by Michal Miroslaw <mirq-linux@rere.qmqm.pl>
