Subject: [PATCH 18/22] mm: mark DEVICE_PUBLIC as broken
Date:   Thu, 13 Jun 2019 11:43:21 +0200
Message-Id: <20190613094326.24093-19-hch@lst.de>

Precedence: bulk

The code hasn't been used since it was added to the tree, and doesn't
appear to actually be usable.  Mark it as BROKEN until either a user
comes along or we finally give up on it.
