For pages that were retained via get_user_pages*(), release those pages via the new put_user_page*() routines, instead of via put_page() or release_pages().
This is part a tree-wide conversion, as described in commit fc1d8e7cca2d ("mm: introduce put_user_page*(), placeholder versions").
This changes the release code slightly, because each page slot in the page_list[] array is no longer checked for NULL. However, that check was wrong anyway, because the get_user_pages() pattern of usage here never allowed for NULL entries within a range of pinned pages.
