Hello Bart,

I applied that patch to your kernel and while I still obviously see all the debug logging its no longer failing fio for me.
I ran 8 loops with 20 parallel fio runs. This was on a different server to the one I had been testing on.

However I am concerned about timing playing a part here here so let us know what you find.

Thanks
Laurence
