Heh.  I tried grepping for "struct page_set" and that showed nothing.  Maybe
"pagegroup"?  Here's a bunch of possible alternatives to set/group:

Maybe consider it a sequence of pages, "struct pageseq"?  page_aggregate
sounds like a possibility, but it's quite long.

Though from an fs point of view, I'd be okay hiding the fact that pages are
involved.  It's a buffer; a chunk of memory or chunk of pagecache with
metadata - maybe something on that theme?
