Yes, there are a few unrelated changes in this patch just to adjust from
the "err" to "ret" symbol. It's relatively minor, so if I send a v5 of
this series, I'll separate those changes to their own precursor patch to
reduce the noise here. Regardless, would you like me to add a
Reviewed-by tag for you for the changes in this patch?
