Comment:

 I've added a commit for the inlining changes -- but I think the (void)
 won't actually stop the compiler from optimizing stuff -- it just tells it
 not to warn us about "counter" being unused.

 For the annotations, I'd rather just run the
 `scripts/maint/annotate_ifdef_directives script from time to time, and let
 that make the changes for me?
