Thanks for checking it, but if you did a review, i.e. if you looked at the code, made suggestions, the submitter acted upon those changes, you looked again, etc, shouldn't this be a more appropriate:
Reviewed-by: Jiri Olsa <jolsa@redhat.com>
?
I think we need to make these tags reflect more what really happened, i.e. if you just glanced over and thought, quickly, that it seems okayish, then Acked-by is what we should use, but if you gone thru the trouble of actually _looking hard_ at it, sometimes multiple times, then we should really use Reviewed-by and not take that lightly.
