Subject: [PATCH 30/34] crypt: convert put_page() to put_user_page*()
Date:   Thu,  1 Aug 2019 19:20:01 -0700
Message-Id: <20190802022005.5117-31-jhubbard@nvidia.com>

Precedence: bulk

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").
