There were queries? My key takeaways were a maintainer NAK followed by
instructions to make the Intel drive align with the driver by
implementing NOIOB. While I disagree with the rejection as it appeared
to be based entirely on politics, I can accept it as the quirk wasn't
in the spec.
It's not fair to make this same "your drive should align with the
driver" demand of Samsung because we *are* talking about a spec'ed
feature here. Technical critques of their patches and real performance
degrades observed are fair game and objective; "your company did
the nastiest possible move violating the normal NVMe procedures to make
it optional" is not.
