Okay, please stop sending new versions now.

We don't want to reach v14 on any patch series. It's a burden on the
developer, the reviewers, the CI, everyone. Please adjust towards
waiting for more review comments before sending another version, and
making the most of each version sent. There are several versions of the
series that didn't receive any feedback; why send another version?

In this case, AFAICT, some of the patches in the series have Reviewed-by
but haven't been changed in the last ten versions of the series. Why
haven't they been merged already? What's the point in resending them
over and over again?


BR,
Jani.
