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