Is it?  Only Kbuild this is related to.

Sorry for the delay.

I have not been able to find time to dive into the detail yet.
(Actually, I tried to do that for v2 or v3, where Python code was so dirty,
then consumed my time to figure out what the code was trying to do)


I find my concern here:
https://lkml.org/lkml/2018/1/5/497


Anyway, I will take a look again when I find some time.
You do not need to take care of the detail until I request to do so.
