[PATCH 2/9] fs/afs/rxrpc: Remove deprecated create_singlethread_workqueue

Show all headers | View raw

The workqueue "afs_async_calls" queues a single work item viz
&call->async_work and hence it doesn't require execution ordering.
Hence, alloc_workqueue has been used to replace the deprecated
create_singlethread_workqueue instance.

The WQ_MEM_RECLAIM flag has been set to ensure forward progress under
memory pressure because the workqueue is being used on a memory reclaim
path.

Since there are fixed number of work items, explicit concurrency
limit is unnecessary here.
