From 1761a85c3bed33591af9a4c2bfac1705c793143f Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Sat, 20 Feb 2016 16:49:50 +0530 Subject: [PATCH] staging: rtl8192u: Remove create_workqueue() With cmwq, use of dedicated workqueues can be replaced by system_wq. Removed the dedicated workqueue and used system_wq instead. Since the work items in the workqueues do not need to be ordered, increase of concurrency by switching to system_wq should not break anything. All work items are sync canceled so it is guaranteed that no work is running when driver is detached.
