I think we need something more like this ...

include/linux/notifier.h:
+static inline int notifier_call_chain(struct notifier_block **n,
+					unsigned long val, void *v)
+{
+	if (n)
+		return __notifier_call_chain(n, val, v);
+	return NOTIFY_DONE;
+}
kernel/sys.c:
-int notifier_call_chain(struct notifier_block **n, unsigned long val, void *v)
+int __notifier_call_chain(struct notifier_block **n, unsigned long val, void *v)
-EXPORT_SYMBOL(notifier_call_chain);
+EXPORT_SYMBOL(__notifier_call_chain);

That way everyone gets both the quick test and the global size reduction.
