I wasn't super keen on that because it felt like forcing three otherwise
separate things into one, but it makes sense if I look at it as corsair_void's
work function.

Is there a guarantee that the same work item won't run twice at the same time?
Do I need to make a work queue for that? I'm also not sure how to pass
arguments to the work function. I'm sure all of that is answered by some
documentation somewhere, but I couldn't find it myself when I looked previously.

Thanks,
Stuart
