    Subject[PATCH v3 37/41] security/tomoyo: convert put_page() to put_user_page*()
    Date
    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").
