Subject: [PATCH 2/9] workqueue: unconfine alloc/apply/free_workqueue_attrs()
Date: Mon, 12 Aug 2019 20:52:17 -0400
Message-ID: <20190813005224.30779-3-daniel.m.jordan@oracle.com> (raw)
In-Reply-To: <20190813005224.30779-1-daniel.m.jordan@oracle.com>

padata will use these these interfaces in a later patch, so unconfine them.
