Subject: [PATCH] qlge: Replace create_singlethread_workqueue with alloc_ordered_workqueue
Date: Sat, 9 Apr 2016 17:27:45 +0530	[thread overview]
Message-ID: <20160409115744.GA30104@amitoj-Inspiron-3542> (raw)

Replace deprecated create_singlethread_workqueue with
alloc_ordered_workqueue.

Work items include getting tx/rx frame sizes, resetting MPI processor,
setting asic recovery bit so ordering seems necessary as only one work
item should be in queue/executing at any given time, hence the use of
alloc_ordered_workqueue.

WQ_MEM_RECLAIM flag has been set since ethernet devices seem to sit in
memory reclaim path, so to guarantee forward progress regardless of 
memory pressure.

Not sure if the assumption of requiring ordering of work items
is correct.
