- * When replacing an anonymous page by a real (!non) swap entry, we clear
- * PG_anon_exclusive from the page and instead remember whether the flag was
- * set in the swp pte. During fork(), we have to mark the entry as !exclusive
- * (possibly shared). On swapin, we use that information to restore
- * PG_anon_exclusive, which is very helpful in cases where we might have
- * additional (e.g., FOLL_GET) references on a page and wouldn't be able to
- * detect exclusivity.

- * These functions don't apply to non-swap entries (e.g., migration, hwpoison,
