Humm, two questions:

Since you changed it that much, wouldn't be better to give you the
authorship while still giving credit to Jiri for the original version?
Something like:

Based-on-a-patch-by: Jiri Olsa

[acme@zoo linux]$ git log | grep Based-on-patch-by: | wc -l
61
[acme@zoo linux]$ git log | grep Based-on-a-patch-by: | wc -l
4
[acme@zoo linux]$ 

But then you need to resubmit this anyway, as you forgot to do the:

 git add tools/perf/tests/topology.c

:-)
