Does this really need a separate workqueue rather than just using
schedule_work()? There doesn't seem to be much point in having its own
workqueue really, to me.

Ah, yes, probably.  I'm not up to date with this kind of thing (last
time I used those, they were called tasklets and bottom halves, you
know... ;) ), so I just followed Documentation/workqueue.txt, which does
not talk about schedule_work.
