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.
