From c1e3dbe9818e3caa4e467255a348df56912ca549 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 28 Jun 2021 19:36:09 -0700 Subject: fs: move ramfs_aops to libfs Move the ramfs aops to libfs and reuse them for kernfs and configfs. Thosw two did not wire up ->set_page_dirty before and now get __set_page_dirty_no_writeback, which is the right one for no-writeback address_space usage. Drop the now unused exports of the libfs helpers only used for ramfs-style pagecache usage.
