+1. NFC = no functional change, and apparently there are changes and they are noticeable.

Multiple things that bother me:

1. I'm not sure that @grokos is indeed the code owner. There was a proposal, but it was never formally accepted. Given that he's now working for a different vendor, does it make sense for him to be owner for code related to Nvidia code?
2. According to the Developer Policy <https://llvm.org/docs/DeveloperPolicy.html#code-owners>:

> Note that code ownership is completely different than reviewers: anyone can review a piece of code, and we welcome code review from anyone who is interested. Code owners are the “last line of defense” to guarantee that all patches that are committed are actually reviewed.

So saying "this is your problem" to a valid review is not appropriate IMO.
