Subject: Re: [Suggestion/Problems] perf annoate: Some problems related to the
 source code view and Improvement of it with line numbers

Hi, Arnaldo :)

Regarding perf annotate:

1) Problem : wrong line numbers on perf-annotate (both stdio and TUI)
2) Problem : wrong sum of overhead(percent) matching source lines
3) Suggestion : new option showing only source code per function
                 with overhead info (to be more readable :) )

I'll send the patchset for them, maybe it'll a bit take time.
But I won't be long..
