inline on static functions makes no sense - the compiler itself is at
liberty to inline any static function that it thinks would benefit,
and it is likely to do so with such a simple function.

Generally we prefer to omit "inline" in .c files and let the compiler
decide whether to inline or not.

What was the reason for making this change?  Do you have a case where
this doesn't happen?
