Yeah, the spec is not very clear on their use. It just defines the codes
and a one sentence description, and then never mentioned again. I think
it allows the possibility for the controller to internally complete a
command with such status from some undefined OOB mechanism. I'm not sure
why the host needs to have their own self-generated status codes anyway
since it can already attach whatever arbitrary flags it wants to its
private data, like how we use NVME_REQ_CANCELLED.

Anyway if a controller did return it for whatever reason, even if it is
a bug, we'd want to see it in the trace.

Sorry, The date is wrong, so I send it again.

I've confirmed what you discussed, and it seems like the approach you
proposed is a better one.
Can I send patch v7 as above?
