Hi Yu,

And please make sure it's disabled by default, because we are still
missing many important functions, e.g., I don't think we can mlock()
when large() && !pmd_mappable(), see mlock_pte_range() and
mlock_vma_folio(). We can fix it along with many things later, but we
need to present a plan and a schedule now. Otherwise, there would be
pushback if we try to land the series without supporting mlock().
Do you or Fengwei plan to take on it? (I personally don't.) If not,
Do you mean the mlock() with large folio? Yes. I can work on it. Thanks.
Great. Thanks!
Other places that have the similar problem but are probably easier to
fix than the mlock() case:
* madvise_cold_or_pageout_pte_range()
This one was on my radar. :).
Regards
Yin, Fengwei
* shrink_folio_list()
