Apply this patch and reproduce it. Is is possible? Didn't we talk about
this already?

Ah, no, mixed patches. Duplication is between other works:
https://lore.kernel.org/all/20260820085347.822-1-xueyao.an@xxxxxxxxxxxxxxxx/
https://lore.kernel.org/all/20260826-shikra-dtpm-v4-1-8476223184de@xxxxxxxxxxxxxxxx/

But nevertheless I am sure we talked about this, that commit msg and is
not accurate... Cannot find the thread, though...

Best regards,
