First, how does this new thing ever get built into the tree?

Second:

This is going to fail to compile on a few platforms, namely m68knommu
and v850 which have configurations that result in using a HZ value
of 50 and 122 respectively.

Otherwise I mostly like all of the new generic stats stuff, although
I do have one question:

+int
+gnet_stats_start_copy_compat(struct sk_buff *skb, int type, int tc_stats_type,
+	int xstats_type, spinlock_t *lock, struct gnet_dump *d)
+{
 ...
+	return gnet_stats_copy(d, type, NULL, 0);

What is this dummy zero-sized RTA_PUT() being done for
(via the gnet_stats_copy() call with size==0 arg)?
