In recent months probably seven maintainers have asked him over and over
(maybe 20 times?) to stop with this nonsense.

Strong responses can occasionally occur if you dare to present special
suggestions for patch reviews according to components in several subsystems.
I tend to interpret hints for improved adherence to Linux development requirements
as helpful so far.

                                               So he knew he shouldn't
have asked Lin Ma to redo the patch.

This contributor could just pick another change idea up in a constructive way.
