Hi,
Thanks so much for trying this patch.
The branch statistics is printed at the end of perf report --stdio.
yep, but for some reason with your changes the head report
got changed as well, I haven't checked the details yet..

The kill returns immediately with no parameter error. Could you try an
application which can run for a while?
For example:
perf record -j any,save_type top
Thanks
