There's now an online LLM-based tool that is automatically reviewing
kernel patches. For this patch set, the results are here:

https://sashiko.dev/#/patchset/20260316121241.910764-1-namjain%40linux.microsoft.com

It has flagged several things that are worth checking, but I haven't
reviewed them to see if they are actually valid.

FWIW, the announcement about sashiko.dev is here:
