Of course, you are entirely free to choose what you want to review, but I t= hink the justification you give is not entirely fair. The patch series was on the list since August, you were explicitly Cc'd fro= m the get-go. In v3 you said: "To be clear, I'm not against the API being merged for the use cases that w= ould benefit from it, but I don't want to see drivers using it to protect from t= he cdev/unregistration race." This was a reply to Bartosz saying: "Yeah, I'm not against this going upstream. If more development is needed f= or this to be usable in other parts of the kernel, that can be done gradually. Literally no subsystem ever was perfect on day 1." Just to be clear, I'm not saying there are no issues to be addressed. And I= 'm also not saying that you never raised concerns, you clearly did. But, given the above, I don't think it's fair to request a revert as a precondition to give constructive feedback for improvements and fixes. - Danilo Link: https://lore.kernel.org/chrome-platform/20250912145416.GL31682@pendra= gon.ideasonboard.com/
