As this condition leads to a VM_BUG_ON(), "pr_debug" seems rather wimpy
and I doubt if we need to be concerned about flooding the console.
I'll switch it to pr_err.
otoh, as nobody has ever hit that VM_BUG_ON() (yes?), do we really need
the patch?
I've hit this bug while developing some code that moves pages between zones.
As it helped me debug that issue with my own code, I could see how
another developer might be helped by it.
