Yes, my future intention is that there will be one *.profraw file per module.
And curiously I would also have renamed the current profile data file to 
"vmlinux.profraw" to disambiguate it from what part of kernel generated it.

I already wrote an small fix up that I think should be part of the upstream 
code so that profiling the vmlinux works better.
It filters out any module originated content from vmlinux.profraw.

Above will be probably a good exercise for me.

Next, my future v2 module profiling machinery
would probably follow on top of your work.

Okay, great; thanks for digging into it! :)
