Thanks, we are well aware, and that is a good reminder for Basak and
me to get our gitdm treeplot patches in shape for proper submission.

Your suspicion, which is counter to my hypothesis, makes this
investigation worthwhile just to see how correct that information
really is.

Maybe the missing or wrong information in MAINTAINERS or the lack of
clear recommendation for new developers to a kernel subsystem on which
integration tree a patch shall apply to is one of the reasons for some
maintainers' misery.
