Thank you for the context!
I think that the current approach is ok, we can go with that, but I wonder whether we can simplify things a bit? What if we prohibit the co-existence of autorelease=on and autorelease=off sockets on the system? The first binding basically locks the kernel path into one way or the other (presumably by using static-branch) and prohibits new bindings that use a different mode. It will let us still keep the mode on the binding and will help us not think about the co-existance (we can also still keep things like one-dmabuf-per-socket restrictions in the new mode, etc).
That approach is okay by me.

I think for you, Mina, this should still work? You have a knob to go back to the old mode if needed. At the same time, we keep the UAPI surface smaller and keep the path more simple. Ideally, we can also deprecate the old mode at some point (if you manage to successfully migrate of course). WDYT?
