Probably because a single btrfs filesystem can be composed of multiple
devices; one major/minor would not be sufficient.

So I'm seeing in the code.

But for the 99% common case (personal computers, one drive), it would be
rather useful it it would comply with filesystem standards there.

In the unlikely event that a btrfs actually is composed of multiple devices,
then in that case perhaps return something nonsensical.

Mmm.. don't we already *have* an LVM layer in Linux?

Seems like a rather bad idea to have a new Linux-specific
filesystem re-implement it's own private LVM, and thus
confuse various disk management tools and the like.
