Subject: [PATCH v2 06/34] drm/i915: convert put_page() to put_user_page*()
Date: Sun,  4 Aug 2019 15:48:47 -0700
Message-ID: <20190804224915.28669-7-jhubbard@nvidia.com> (raw)
In-Reply-To: <20190804224915.28669-1-jhubbard@nvidia.com>

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").

This is a merge-able version of the fix, because it restricts
itself to put_user_page() and put_user_pages(), both of which
have not changed their APIs. Later, i915_gem_userptr_put_pages()
can be simplified to use put_user_pages_dirty_lock().
