Hmm, my only concern on that front is that we'd be backporting effectively new functionality to stable@ kernels that isn't strictly necessary. But that's probably fine given that it requires userspace to opt-in.
Yeah. Arguably it's *all* a new capability and a 'new' (albeit 30 years old!) feature.
I guess you could make an argument for *only* backporting the DISABLE part to stable kernels and not the ENABLE part.... but don't :)
