From: Bhaktipriya Shridhar Date: Tue, 30 Aug 2016 16:49:11 +0000 (+0530) Subject: dm bufio: remove use of deprecated create_singlethread_workqueue() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=edd1ea2a8a2549e4fe58e817d539445729491ecf;p=openwrt%2Fstaging%2Fblogic.git dm bufio: remove use of deprecated create_singlethread_workqueue() The workqueue "dm_bufio_wq" queues a single work item &dm_bufio_work so it doesn't require execution ordering. Hence, alloc_workqueue() has been used to replace the deprecated create_singlethread_workqueue(). The WQ_MEM_RECLAIM flag has been set since DM requires forward progress under memory pressure. Since there are fixed number of work items, explicit concurrency limit is unnecessary here.
