Subject: [PATCH v2 8/8] power: ds2760_battery: Remove deprecated create_singlethread_workqueue
Date: Tue, 16 Aug 2016 10:54:06 +0530 [thread overview]
Message-ID: <7c1c19df679dd438c4351909f55169583d9386b3.1471324750.git.bhaktipriya96@gmail.com> (raw)
In-Reply-To: <cover.1471324749.git.bhaktipriya96@gmail.com>
alloc_ordered_workqueue() with WQ_MEM_RECLAIM set replaces
deprecated create_singlethread_workqueue(). This is the identity
conversion.
The workqueue "monitor_wqueue" is used to monitor the battery
status. It has been identity converted.
It queues multiple work items viz &di->monitor_work,
&di->set_charged_work, which require execution ordering.
Hence, alloc_workqueue has been used to replace the
deprecated create_singlethread_workqueue instance.
WQ_MEM_RECLAIM flag has been set to ensure forward progress under
memory pressure.
