I'd love to apply this, but somewhere along the way the patch has been white space damaged. Can you resend this patch gzip'ed or something like that, to ensure that it doesn't get modified along the way? Bonus points if you re-indent, fio uses real tabs and not 4 spaces. Not a huge problem, I'll just lindent it as-is if need be. It'd be great to have a small job file included as well for testing, and an example of a result using that job file. -- Jens Axboe
