At midnight the AI review from the netdev patchwork correctly identified a
problem with the above code:

https://netdev-ai.bots.linux.dev/ai-review.html?id=fb201338-eed0-488f-bb32-5240af254cf4

Is the review sent exclusively in a direct email or available in a
mailing list?

No. I have checked the status of our PR in patchwork yesterday:

https://patchwork.kernel.org/project/netdevbpf/list/?series=1042268

And I was wondering why my patch was marked "yellow"

https://patchwork.kernel.org/project/netdevbpf/patch/20260114105212.1034554-4-mkl@pengutronix.de/

The AI review marked the patch as "yellow" but the review result was not 
accessible until midnight.

A direct feedback to the authors would be helpful.
