From 4c136dae62f7a62383a9d6563c8613e732bfefaf Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Sun, 4 Sep 2016 20:54:11 +0530 Subject: [PATCH] fs/afs/callback: Remove deprecated create_singlethread_workqueue The workqueue "afs_callback_update_worker" queues multiple work items viz &vnode->cb_broken_work, &server->cb_break_work which require strict execution ordering. Hence, an ordered dedicated workqueue has been used. Since the workqueue is being used on a memory reclaim path, WQ_MEM_RECLAIM has been set to ensure forward progress under memory pressure.
