Hm, I missed this first time around:

 - why is this function global? It's not used by anything else.

 - why is it squeezed before a structure without any vertical 
   separation?

 - why does it have the body as { }, as if it were an inline 
   function?

Really, this should either be a short static function, with a 
proper body, or we should accept a NULL pointer there and check 
for it before calling it - there's a single usage site right 
now.

The latter looks like the cleanest solution to me.

Thanks,
