[PATCH] perf report: Add a tip about source line numbers with overhead
From: Kim SeonYoung
Date: Thu Sep 29 2016 - 18:01:40 EST
There is a existing tip as below.
If you have debuginfo enabled, try: perf report -s sym,srcline
However this tip only describe a condition to use --sort sym,scrline options.
So there is lack of explanation in the tip. I think that it would be better to
add a tip that exactly explain the feature of --sort srcline.
