You could save another compound_head() call by passing the folio through
to migrate_vma_insert_page() and make it migrate_vma_insert_folio(),
since its already converted to use folios.
Sure, but let's do it later, we could convert more functions in
migrate_device.c to use folios, thanks for your review, do you
mind to help to review other patches, hope that the poison recover
from migrate folio was merged firstly.
