From b2990536f44752e54dc300a2f98253519adfe649 Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Wed, 31 Aug 2016 00:33:25 +0530 Subject: scsi: mpt: Remove deprecated create_singlethread_workqueue The workqueues "ioc->reset_work_q" and "ioc->fw_event_q" queue a single work item &ioc->fault_reset_work and &fw_event->work, respectively and hence don't require ordering. Hence, they have been converted to use alloc_workqueue(). The WQ_MEM_RECLAIM flag has been set to ensure forward progress under memory pressure since the workqueue belongs to a storage driver which is being used on a memory reclaim path. Since there are fixed number of work items, explicit concurrency limit is unnecessary here. Signed-off-by: Bhaktipriya Shridhar Acked-by: Tejun Heo Signed-off-by: Martin K.
