Ah ok.

Yeah, I think "struct rmpread" is simply a strange thing to have when there is
an instruction of that name. I think the naming of the structs should aim at
being descriptive as to what they are. Hypothetical example:

struct rmpentry_as_found_in_the_rmptable ...

struct rmpentry_as_returned_by_rmpread

Now make the above shorter by keeping the information. :-)

IOW, on the one hand, "rmpentry_raw" or "rmpentry_direct" or
"rmpentry_<something>", and, OTOH, just "struct rmpentry" kinda makes sense
and it is short enough.

At least how I see it rn...

Thx.
