From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bhaktipriya Shridhar Subject: [PATCH] dm-bufio: Remove deprecated create_singlethread_workqueue Date: Tue, 30 Aug 2016 22:19:11 +0530 Message-ID: <20160830164911.GA26756@Karyakshetra> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org To: Alasdair Kergon , Mike Snitzer , dm-devel@redhat.com, Shaohua Li Cc: Tejun Heo , linux-raid@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: linux-raid.ids The workqueue "dm_bufio_wq" queues a single work item &dm_bufio_work and hence 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 since md / dm are block multi disk drivers and require forward progress under memory pressure. Since there are fixed number of work items, explicit concurrency limit is unnecessary here.
