Subject: [PATCH] Check net->nfnl for NULL in ctnetlink_conntrack_event to,
 avoid Oops on container destroy

Patrick,

I received this patch from a developer that uses lxc and network name 
spaces. I don't know the locking semantics well enough for CT to judge 
whether this fix is sufficient. Bug info can be found at 
http://bugs.launchpad.net/bugs/843892 . See comment #7 for his analysis.
