Subject: [RFC PATCH 5/8] Convert net wireless tasklet to workqueue
Content-Disposition: inline; filename=convert-net-wireless-tasklet-workqueue.patch
Sender: linux-kernel-owner@vger.kernel.org
X-Mailing-List: linux-kernel@vger.kernel.org

Since we want to remove DECLARE_TASKLET API, there wasn't a simple way
to do that elegantly with net/core/wireless.c, so this patch just
replaces that tasklet with a work queue directly.
