kthread with kpause or callout


I'm writing a keyboard driver which doesn't support interrupts in some
revisions, so I have to poll its status from time to time. What would
be better suited for that task:

- Running a kthread and calling kpause() between the polls.
- Using a callout which reschedules itself after the poll.

Or is there something even better suited, which I'm missing?
