From b3ac04132c4b9bc5c9c14608424d410e7ca3b400 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Fri, 21 Jan 2022 11:27:31 -0500 Subject: mm/rmap: Turn page_referenced() into folio_referenced() Both its callers pass a page which was previously on an LRU list, so were passing a folio by definition. Use the type system to enforce that and remove a few calls to compound_head().
