SubjectRe: [PATCH 1/5] trace: do not disable wake up tracer on output of trace

On the other hand - the latencies caused by tracing output itself should be
quite low, correct? If not then that needs fixing too. So i've picked up
your change - lets see how useful the result is.

But "if it hurts, disable tracing before reading the tracing result" method
you expressed is really not acceptable.
