Thanks for your feedback.

I am sorry for a bit of confusion here.

1. Would it make sense that a variant for the thunderbolt ring_free()
   function will also perform input parameter validation?

2. Are any additional prefixes appropriate so that further name space
   conflicts can be better avoided?

Regards,
Markus
