I thought about placing this patch before the previous one, but it
turned a bit easier for me to split the changes in the reverse order.
It has made this patch a bit smaller and more coherent. But seeing you
weren't happy with too many changes in the previous patch I'll do as
you suggest and change the patches order. Since the patch content will
be changed I won't add your reviewed-by tag there on v2. So please
consider re-reviewing it one more time.
