Subject: [PATCH v2 3/3] net/xdp: convert put_page() to put_user_page*()
Date: Tue, 23 Jul 2019 18:26:06 -0700	[thread overview]
Message-ID: <20190724012606.25844-4-jhubbard@nvidia.com> (raw)
In-Reply-To: <20190724012606.25844-1-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

This is part a tree-wide conversion, as described in commit fc1d8e7cca2d
("mm: introduce put_user_page*(), placeholder versions").
