From 6e1cae881a0646f31fe2bda90297d820da1137eb Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Mon, 28 Jun 2021 19:36:15 -0700 Subject: mm/writeback: move __set_page_dirty() to core mm Patch series "Further set_page_dirty cleanups". Prompted by Christoph's recent patches, here are some more patches to improve the state of set_page_dirty(). They're all from the folio tree, so they've been tested to a certain extent. This patch (of 6): Nothing in __set_page_dirty() is specific to buffer_head, so move it to mm/page-writeback.c. That removes the only caller of account_page_dirtied() outside of page-writeback.c, so make it static.
