Subject: [PATCH v3 35/41] kernel/events/core.c: convert put_page() to put_user_page*()
Date:   Tue,  6 Aug 2019 18:33:34 -0700

From: John Hubbard <jhubbard@nvidia.com>

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").
