Why? You can parse partition table in userspace (initramfs) and use
BLKPG_ADD_PARTITION ioctl to inform kernel about the disk layout or
you can use device-mapper to create new devices.
IMHO we don't use this concept, because the current way (parse all in
kernel) works usually fine.
(If I good remember partitioned DM devices are already managed from
userspace and PT is not parsed in kernel.)
