From: "Matthew Wilcox (Oracle)" <willy@xxxxxxxxxxxxx> Subject: fs: remove anon_set_page_dirty() Use __set_page_dirty_no_writeback() instead. This will set the dirty bit on the page, which will be used to avoid calling set_page_dirty() in the future. It will have no effect on actually writing the page back, as the pages are not on any LRU lists.
