Re: the difference between btt and blkparse

Oh. I think I misunderstood the option usage.

I orginally used "blkparse -i trace.blkparse.* -d bp.bin". However it
handled number of cpu times, instead of one. "blkparse -i
trace.blkparse.0" and "blkparse -i trace.blkparse.1" have the same

While for btt, I orginally used "btt -i trace.blkparse.*". However the
result was only to handle trace.blkparse.0, instead of others. So the
two results were not match.

Now I will stick to the standard workflow.

Thanks for your help.
