And this seems have avoided breaking things, so I moved it on top of the
earlier srcunmisafe.2022.11.09a stack with a new srcunmisafe.2022.11.29a
branch name.

If you need me to, I can push this into the upcoming merge window.
Or you could rebase on top of it, so that when the printk() series goes
in, this commit will come along for the ride.

Your choice, just let me know!

Thanx, Paul
