Have you assessed that? (trimmed long cc: list to keep it sane, I'll not use get_maintainer.pl output this way anymore) I'm not sure it decreases performance. From the last iteration of the patch, I removed the hint to force "not inlining", so that gcc can inline it if it thinks it's better. Are those so performance sensitive that it makes sense to perform this assessment? If you think so, what would you suggest? A micro-benchmark or some real use case?
