I can see ~10k insertions over ~1k commits and 15 years that mention a
fallthrough in the entire repo. That is including some commits (like
the biggest one, 960 insertions) that have nothing to do with C
fallthrough. A single kernel release has an order of magnitude more
changes than this...

But if we do the math, for an author, at even 1 minute per line change
and assuming nothing can be automated at all, it would take 1 month of
work. For maintainers, a couple of trivial lines is noise compared to
many other patches.

In fact, this discussion probably took more time than the time it
would take to review the 200 lines. :-)

Accepting trivial and useful 1-line patches is not what makes a
voluntary maintainer quit... Thankless work with demanding deadlines is.

I have not said that, at all. In fact, I am a voluntary one and I
welcome patches like this. It takes very little effort on my side to
review and it helps the kernel overall. Paid maintainers are the ones
that can take care of big features/reviews.

I understand your point, but you were the one putting it in terms of a
junior FTE. In my view, 1 month-work (worst case) is very much worth
removing a class of errors from a critical codebase.

That may very well be true, but I don't feel anybody has devalued
maintainers in this discussion.

Cheers,
Miguel
