XFS will always require a random writable area for metadata. I have
an old early draft with a fully zone aware allocator essentially
replacing the realtime subvolume. But it's been catching dust so far,
maybe I'll have a chance to resurrect it if I don't have too fight too
many stupid patchseries all at once.
