From d9c08e2232fbca4fa56b9350f7f84835c4aa3add Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Sun, 28 Feb 2021 16:02:57 -0500 Subject: mm/rmap: Add folio_mkclean() Transform page_mkclean() into folio_mkclean() and add a page_mkclean() wrapper around folio_mkclean(). folio_mkclean is 15 bytes smaller than page_mkclean, but the kernel is enlarged by 33 bytes due to inlining page_folio() into each caller. This will go away once the callers are converted to use folio_mkclean().
