Yep, I've rolled back to fio-2.1.13-77-g0f9940a, which is what I had
been using previously for a long time, and the problem with
generic/299 seems to have gone away. I had hoped that the days when
new releases of fio wouldn't intrdouce random new bugs was a temporary
aberration, but obviously that was a bit over-optimistic.
