From: Bhaktipriya Shridhar Date: Sat, 10 Sep 2016 10:34:01 +0000 (+1000) Subject: fs/ocfs2/dlm: remove deprecated create_singlethread_workqueue() X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=320eee3474bb1a149eff886e11dacf180c9b6ee3;p=deliverable%2Flinux.git fs/ocfs2/dlm: remove deprecated create_singlethread_workqueue() The workqueue "dlm_worker" queues a single work item &dlm->dispatched_work and thus 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. Since there are fixed number of work items, explicit concurrency limit is unnecessary here.
