Since there's questions about this pull request seeming to be the
first time this patch has appeared on list, I'll go ahead and review
it here on the assumption that a v2 pull request is warranted.

Is it possible to put this closer to the code actually using 'nbd', as
in this region?

but then again, open_nbd() right after your current location utilizes
the variable, so I guess not. I trust your judgment on silencing the
linters, so whether or not you move it (if moving is even possible),
