Maybe I wasn't 100% clear, but what I mean is that patches 1 and 2 don't
apply to the upstream kernel, as they are sitting on top of other
patches that block block/bdev.c in your tree. So even if acked, they
can't go in as-is. Well they can, I'd just have to hand apply them.
Which isn't the end of the world, but the dependency wasn't clear (to
me, at least) in the sent out patches.
