BTW, I keep getting confused by the topic.

Isn't this essentially

"mm: support device-private THP"

and the support for migration is just a necessary requirement to *enable* device private?


I agree, I can change the title, but the focus of the use case is to
support THP migration for improved latency and throughput. All of that
involves support of device-private THP

Well, the subject as is makes one believe that THP support for zone-device pages would already be there, and that you are adding migration support.

That was the confusing part to me, because in the very first patch you add ... THP support for (selected/private) zone device pages.
