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". Linus
