But it applies well enough and is adequately reviewed so I put it in there for testing, thanks. AI review might have found a couple of pre-existing binder bugs: https://sashiko.dev/#/patchset/20260813193433.3318288-1-surenb@google.com and a small rusty thing which you might wish to attend to. > Binder and networking folks: Your code is the target of the cleanups. > I'm cc'ing you now on v2 because there's emerging consensus on the mm > side that the approach here is sane.

More binder/net acks would be helpful, please.
