Arnd, have you seen this? We haven't heard anything from Shawn afaics,
who normally would take care of a patch like this. Hence could you
consider picking up the patch at the start of this thread (e.g.
https://lore.kernel.org/all/20221205152327.26881-1-francesco@dolcini.it/
) and send it to Linus in the next 48 hours? It seems low-risk and fixes
a regression introduced this cycle various people care about. That's why
I'll likely ask Linus to consider picking this up directly before
releasing 6.1, if I don't hear anything from you soon. But I'd prefer if
the patch would go through at least somewhat the proper channels;
alternatively a ACK from you to signal Linus "yeah, pick this up" would
help as well.

Ciao, Thorsten
