From 919a295abf968cec6ffd3c629241b2e626cf0f5d Mon Sep 17 00:00:00 2001 From: Bob Liu Date: Fri, 3 Jul 2020 13:16:03 +0800 Subject: [PATCH] scsi: iscsi: Register sysfs for workqueue iscsi_destroy Register sysfs for workqueue iscsi_destroy so that users can set CPU affinity through "cpumask" for this workqueue to get better isolation in cloud multi-tenant scenario. This patch unfolded create_singlethread_workqueue(), added WQ_SYSFS and drop __WQ_ORDERED_EXPLICIT since __WQ_ORDERED_EXPLICIT workqueue isn't allowed to change "cpumask".
