From 44be975691703cda8e23fe45296f78b287e40232 Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Fri, 7 Oct 2016 16:57:13 -0700 Subject: fs/ocfs2/super: remove deprecated create_singlethread_workqueue() The workqueue "ocfs2_wq" queues multiple work items viz &osb->la_enable_wq, &journal->j_recovery_work, &os->os_orphan_scan_work, &osb->osb_truncate_log_wq which require strict execution ordering. Hence, an ordered dedicated workqueue has been used. WQ_MEM_RECLAIM has been set to ensure forward progress under memory pressure because the workqueue is being used on a memory reclaim path.
