Is there a way to get fio to generate a log file for all 8 workers, instead of 8 separate files? That is untenable. I had to go back to 2.1.8 to get a useable output. It's not like the data outputs are very friendly anyway, but with one file at least that data can easily be parsed and worked with. With a different file for each worker it is just ridiculous.

Lets back this up a bit. Your bug reporting _sucks_. Constructive 
criticism - look it up. You were even lazy enough to just reply to an 
old, totally unrelated email, instead of starting a new thread.

So lets try this again. I'll even offer you some free hints. Find out 
where the change happened, see if there's reasoning there. If not, 
suggest a way to improve the situation. Or even just, constructively, 
suggest why the current behavior is a problem and offer your opinion on 
how it could be improved to make your life easier. Nobody on this list 
owes you anything, you need to earn it.
