Maybe because of this, sashiko was unable to review this. To my understanding, there is no real reason to make this based on damon/next. And I'd like to get sashiko review for this patch. Could you please rebase this to latest mm-new and repost for that? > > Background and Motivation > ========================= > > In heterogeneous memory systems, controlling memory distribution across > NUMA nodes is essential for performance optimization.

[...] Other than the lack of the sashiko review, this cover letter looks good to me. Thanks, SJ [...]
