Jens,
Finally got back to this.
I do get different results with 2.1.6.1.
Not sure what is wrong.

OK, will grab 2.1.6 and reply with observations.
I've only recently subscribed to this mail-list and it amazes me that you can give attention to such a barrage of requests.

Thanks for the detailed report. But why are you replaying with fio-2.1.4? If there's a bug here (and it looks like it), then please replay the blktrace with fio-2.1.6 and I can take a look at it.
