I suspect we _could_ do this with an auto-detect macro?

#if ... /* < 5.5 */
#define u64_stats_inc(v) (*v)++
#define u64_stats_add(v, a) (*v)+=3D(a)
#else
#define u64_stats_inc(v) \
 do {
	if (__builtin_types_compatible(typeof(v), *u64_stats_t)
		u64_stats_inc(v);
	else
		(*v)++;
 } while(0)


or so?

But then it's only one driver here ...
