This series is reviving an old patchwork.
Booting from a mapped device requires an initramfs. This series is
allows for device-mapper targets to be configured at boot time for
use early in the boot process (as the root device or otherwise).

What is the reason for this patch series?
Setting up non-trivial root filesystems/storage always requires an
initramfs, there is nothing
wrong about this.

Exactly.  If phones or whatever would benefit from this patchset then
say as much.

I will not accept this patchset at this time.

Example, the following could be added in the boot parameters.
dm="lroot,,,rw, 0 4096 linear 98:16 0, 4096 4096 linear 98:32 0" root=/dev/dm-0

Hmmm, the new dm= parameter is anything but easy to get right.

No, it isn't.. exposes way too much potential for users hanging
themselves.
