alloc_workqueue replaces deprecated create_workqueue(). A dedicated workqueue has been used since the workitems are involved in normal device operation. Workitems &priv->rx_work and &priv->tx_work, map to w5100_rx_work and w5100_tx_work respectively and are involved in receiving and transmitting packets. Forward progress under memory pressure is a requirement here. create_workqueue has been replaced with alloc_workqueue with max_active as 0 since there is no need for throttling the number of active work items. Since the driver may be used in memory reclaim path, WQ_MEM_RECLAIM has been set to guarantee forward progress. 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 <bhaktipriya96@gmail.com> Acked-by: Tejun Heo <tj@kernel.org> Signed-off-by: David S.
