From 0a91605cda883f7a25b1e7fa8cdc3f633ae8f8e0 Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Tue, 26 Jul 2016 22:38:24 +0530 Subject: [PATCH] net/mlx5_core/health: Remove deprecated create_singlethread_workqueue The workqueue health->wq was used as per device private health thread. This was done to perform delayed work. The workqueue has a single workitem(&health->work) and hence doesn't require ordering. It is involved in handling the health of the device and is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. Work item has been flushed in mlx5_health_cleanup() to ensure that there are no pending tasks while disconnecting the driver.
