From: Bhaktipriya Shridhar Date: Tue, 7 Jun 2016 20:17:59 +0000 (+0530) Subject: net: cavium: liquidio: Remove deprecated create_workqueue X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=292b9dab403973a8644cdb84d8e46bd4e6b4baa2;p=linux-beck.git net: cavium: liquidio: Remove deprecated create_workqueue alloc_workqueue replaces deprecated create_workqueue(). A dedicated workqueue has been used since the workitem viz (&lio->txq_status_wq.wk.work which maps to octnet_poll_check_txq_status) is involved in a brief poll routine for checking transmit queue status and is an intergral part of 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.
