Bhaktipriya Shridhar f0200c0288 ps3: Remove deprecated create_singlethread_workqueue ... The workqueue "ps3av->wq" queues a single work item &ps3av->work and hence doesn't require ordering. It is involved in waking up ps3avd to do the video mode setting and hence it's not being used on a memory reclaim path. Hence, it has been converted to use system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. The work item has been flushed in ps3av_remove to ensure that there are no pending tasks while disconnecting the driver.
