I can agree to this view in principle according to the required control flow.

How does this wording fit to information from the section
“7) Centralized exiting of functions” in the document “coding-style.rst”?

Would you like to clarify the current situation around supported
software optimisations any more?

Do we stumble on different coding style preferences once more?

Thanks for another bit of positive feedback.

Do Linux guidelines need any adjustments?

I tried to apply another general source code transformation pattern.

Why?
I hope also that the source code can be kept consistent to some degree.

I would find such a communication style questionable.
Do you distinguish between bug fixes and possible corrections for
other error categories (or software weaknesses)?
