alloc_workqueue replaces deprecated create_workqueue(). A dedicated workqueue has been used since the workitem (viz &fault->work), is involved in IO page-fault handling. WQ_MEM_RECLAIM has been set to guarantee forward progress under memory pressure, which is a requirement here. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary.
