If that's incorrect, would you please give me a hint how to set
__WQ_ORDERED(internal use flag) and WQ_HIGHPRI flags at the same time?
Wouldn't alloc_ordered_workqueue(NAME, WQ_HIGHPRI, ...) do what you want?
That was my initial suggestion. Can WQ_HIGHPRI be used together with
WQ_MEMRECLAIM?

I was trying do that, but the comment of alloc_oredered_workqueue shows
that only WQ_FREEZABLE and WQ_MEM_RECLAIM are meaningful, so...
I will measure the throughput with "alloc_ordered_workqueue(NAME,
WQ_HIGHPRI, ...)" to see if WQ_HIGHPRI works with
alloc_ordered_workqueue. Thanks for the suggestion.
