do not touch tracing_thresh
The -b argument is for stopping the cyclictest when it misses a wakup
by that # microseconds. Setting the tracing_thresh causes the latency tracer
to ignore any latency under tracing_thresh. These two meanings are completely
agnostic to each other, and should not be the same. We want the max latency,
that should be good enough. Not only those that are bigger than our missed
deadline. That misses most of our traces that we want.
