   This was the case for an older version of nfnetlink. With 
nfnetlink-ctnetlink 0.13 you should use

static struct notifier_block my_notifier = {
	my_notifier_function,
	NULL,
	0
};

   For more info see that patch, it actually _uses_ notifiers to be able 
to catch conntrack entry related events. Note that this interface is much 
more universal, for example you can catch events when a conntrack entry is 
modified, etc. Good luck :)
