From b82a96c9253333a8834b2df5f262a39cccf4f6c7 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Mon, 28 Jun 2021 19:36:27 -0700 Subject: fs: remove noop_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.
