I think you've mis-interpreted what Dan said

The message @
http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1441839.html
states

"I was suggesting MEMORY_DEVICE_HOST for persistent memory and
MEMORY_DEVICE_PUBLIC as you want for CDM."

I guess we get to keep DEVICE_PUBLIC and move persistent memory
to MEMORY_DEVICE_HOST
