From: John Hubbard <jhubbard@xxxxxxxxxx>
For pages that were retained via get_user_pages*(), release those pages
via the new put_user_page*() routines, instead of via put_page().
This is part a tree-wide conversion, as described in commit fc1d8e7cca2d
("mm: introduce put_user_page*(), placeholder versions").
