Subject: [Intel-wired-lan] [PATCH] net: ethernet: intel: fm10k: Remove create_workqueue
alloc_workqueue replaces deprecated create_workqueue().
A dedicated workqueue has been used since the workitem (viz fm10k_service_task, which manages and runs other subtasks) is involved in normal device operation and requires forward progress under memory pressure.
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 network devices 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.
