man 2 migrate_pages says:
RETURN VALUE
On success migrate_pages() returns the number of pages that could not be moved (i.e., a return of zero means
that all pages were successfully moved). On error, it returns -1, and sets errno to indicate the error.
which implies that it doesn't return until an attempt has been made to migrate all relevant
pages. And that rules out lazy migration.
What problem are you trying to solve by doing it in a lazy manner?
