err, actually, it gets messy.

Can we please have a v4? I think there are a few other things pending?

I've noted
https://lkml.kernel.org/r/acqrtd7E6UxrX6Ji@xxxxxxxxxxxxxxxxxxxx and
https://lkml.kernel.org/r/202603311743.uZYPu1Gn-lkp@xxxxxxxxx

Alternatively, I can leave the current series in mm-unstable as-is and
we can add a fixup at end-of-series. Not ideal, but it's OK.
