While looking at this, I think there is another issue. When a hugetlb page is migrated, we do not migrate the 'page_huge_active' state of the page. That should be moved as the page is migrated. Correct?
Yes, and I think that putback_active_hugepage(new_hpage) at the last step of migration sequence handles the copying of 'page_huge_active' state.
Thanks! I missed the putback_active_hugepage that takes care of making the target migration page active.
