From: Bhaktipriya Shridhar Date: Sat, 4 Jun 2016 14:51:40 +0000 (+0530) Subject: net: ethernet: cavium: liquidio: response_manager: Remove create_workqueue X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=523a61b488afb51af18729d8300b7f624761370f;p=linux-beck.git net: ethernet: cavium: liquidio: response_manager: Remove create_workqueue alloc_workqueue replaces deprecated create_workqueue(). A dedicated workqueue has been used since the workitem viz (&cwq->wk.work which maps to oct_poll_req_completion) 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. Hence the call to flush_workqueue() has been dropped. Signed-off-by: Bhaktipriya Shridhar Signed-off-by: David S.
