Subject: [PATCH] security/tomoyo: convert put_page() to put_user_page*()
Date: Sun, 4 Aug 2019 19:26:26 -0700 [thread overview]
Message-ID: <20190805022626.13291-1-jhubbard@nvidia.com> (raw)
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").
