A dedicated workqueue has been used since the work items are being used on a memory reclaim path. WQ_MEM_RECLAIM has been set to guarantee forward progress under memory pressure. The workqueue has a single work item. Hence, alloc_workqueue() is used instead of alloc_ordered_workqueue() since ordering is unnecessary when there's only one work item. Explicit concurrency limit is unnecessary here since there are only a fixed number of work items.
