Actually, maybe I can backtrack on that a bit.

Maybe 'pageset' would work as a name. It's not used as a type right
now, but the usage where we do have those comments around 'struct
per_cpu_pages' are actually not that different from the folio kind of
thing. It has a list of "pages" that have a fixed order.

So that existing 'pageset' user might actually fit in conceptually.
The 'pageset' is only really used in comments and as part of a field
name, and the use does seem to be kind of consistent with the Willy's
use of a "aligned allocation-group of pages".
