Hi,
this patch reduces false positives in the detection of bfq_queues
associated with soft real-time applications. As such, this patch
reduces the damages caused by these false positives to other
applications. The patch proved to be very effective, as detailed in
the commit message. A sort of counterpart of this patch should follow
soon, this time for false positives in the detection of cooperating
processes (processes doing I/O close to each other).

I guess it is evidently too late for 4.15, so, Jens, please consider
this patch for 4.16. Of course if the patch turns out to be ok.

Added for 4.16, thanks.
