Subject: [PATCH] Bluetooth: Remove deprecated create_singlethread_workqueue
Date: Tue, 30 Aug 2016 22:42:53 +0530 [thread overview]
Message-ID: <20160830171252.GA32272@Karyakshetra> (raw)
The workqueue "workqueue" queues multiple work items viz &qca->ws_awake_rx
&qca->ws_rx_vote_off, &qca->ws_awake_device, &qca->ws_tx_vote_off which
require strict execution ordering. Hence, an ordered dedicated workqueue
has been used to replace the deprecated create_singlethread_workqueue
instance.
WQ_MEM_RECLAIM has not been set since the driver is not being used on a
memory reclaim path.
