I think the changelog for this series of conversions
should show that you've validated the change by
inspecting the return call chain at each modified line.

Also, it seems you've cc'd the same mailing lists for
all of the patches modified by this series.

It would be better to individually address each patch
in the series only cc'ing the appropriate maintainers
and mailing lists.

A cover letter would be good too.
