Subject: [PATCH net-next 9/9] fs/afs/flock: Remove deprecated

From: Bhaktipriya Shridhar <>

The workqueue "afs_lock_manager" queues work item &vnode->lock_work,
per vnode. Since there can be multiple vnodes and since their work items
can be executed concurrently, 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

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