Sounds good to me, I didn't realise that both the original series at [0]) (which introduced the test fail) and the follow up at [1] were intended to be dropped, I thought only [1] but dropping [0] obviously also fixes it! And it looks like Andrew's done so and tests now fully working in mm-new again so I'm happy :) Cheers, Lorenzo [0]:https://lore.kernel.org/all/20250718172138.103116-1-pfalcato@xxxxxxx/ [1]:https://lore.kernel.org/all/20250812162124.59417-1-pfalcato@xxxxxxx/
