Sorry for the delay.

I would like to discuss the following topics:



* Hugepage migration ? Currently, hugepage is not migratable and can?t
use pages in ZONE_MOVABLE.  It is not happy from point of CMA/hotplug
view.

migrate_huge_page() ?

It seems that migrate_huge_page just called in memory failure path, why can't support in memory hotplug path?


It's also possible to allocate hugetlbfs pages in ZONE_MOVABLE but must
be enabled via /proc/sys/vm/hugepages_treat_as_movable.

* Remove ZONE_MOVABLE ?Very long term goal. Maybe not suitable in this year.

Whatever about removing it totally I would like to see node memory hot-remove
not depending on ZONE_MOVABLE.
