    I recognize that it could be challenging finding a consensus to update
    CODING_STYLE but it might be worth doing to reduce frictions with both
    contributors and other reviewers.
    
    But to be clear, I was also referring to things that might be actually
    hard to add to CODING_STYLE, such as macro vs. static inlines, when to
    split a single function into multiple smaller functions, etc.
    
I think this is definitely something we ought to do. I am volunteering to
pick this up, but changing/clarifying the CODING_STYLE needs to be 
considered in conjunction with checking tools

I have parked this for now, as
a) I did not want to disrupt 4.13 
b) and until recently I also didn’t fully understand what kind of coding
standards would help with safety certification

And of course, having a bot do the checking would remove the friction
entirely.
