Note that this is not my patch, and I hadn't posted anything on the thread when Thomas sent that email? So I'm not sure what you're even referring to here as me having failed to do. If you think the explanation of my use cases I have since sent is insufficient, I'm happy to reply to that/expand on them, but you're going to have to be a bit more specific on why I "failed to describe any".

I just don't see why a simple "what's the use case" wouldn't be a lot more productive than this posturing. Particularly on a thread that is explicitly inviting people from outside the core kernel dev community to chime in.
