I think we're in the same line here really :-) And apologies for
over-reacting, I definitely went over the top!

I did the marshaller/unmarshaller exactly for Rust TPM driver only in
the sense that if I got a patch set on my table doing that, it would be
the part which is complex enough that I would actually be in trouble.
So consider it like "years ahead preparation".

I quickly went through your list as a reality check if I have blind
spot but for the most part it is "business as usual" type of stuff,
some to change done many years ago (at least as old as tpmrm0).

Obvious exception to the rule are bugs related to HMAC encryption
to which I think we have now a resolution.
