From aaa76724d7ece87eb5f66e02fac9da036dd20667 Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Sat, 4 Jun 2016 20:54:00 +0530 Subject: [PATCH] net: ethernet: cavium: liquidio: request_manager: Remove create_workqueue alloc_workqueue replaces deprecated create_workqueue(). A dedicated workqueue has been used since the workitem viz (&db_wq->wk.work which maps to check_db_timeout) is involved in normal device operation. WQ_MEM_RECLAIM has been set to guarantee forward progress under memory pressure, which is a requirement here. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary. flush_workqueue is unnecessary since destroy_workqueue() itself calls drain_workqueue() which flushes repeatedly till the workqueue becomes empty.
