Subject: [PATCH 1/3] sgi-gru: Convert put_page() to get_user_page*()
Date: Sun, 21 Jul 2019 21:28:03 +0530 [thread overview]
Message-ID: <1563724685-6540-2-git-send-email-linux.bhar@gmail.com> (raw)
In-Reply-To: <1563724685-6540-1-git-send-email-linux.bhar@gmail.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().
This is part a tree-wide conversion, as described in commit fc1d8e7cca2d
("mm: introduce put_user_page*(), placeholder versions").
