Subject: [PATCH v2 25/34] mm/frame_vector.c: convert put_page() to put_user_page*()

From: John Hubbard <[email protected]>

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").
