No worries, ask away if you have questions. As you might have seen, it's still a little bit of a moving target, but it's getting closer every day. I'll post a v3 later today hopefully that will be a good fix point for you. I'll need to add the io context setup etc, that's not there yet, as only cfq/bfq uses that.
