From b97cca3ba9098522e5a1c3388764ead42640c1a5 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Thu, 3 Feb 2022 08:29:21 -0800 Subject: xfs: only bother with sync_filesystem during readonly remount In commit 02b9984d6408, we pushed a sync_filesystem() call from the VFS into xfs_fs_remount. The only time that we ever need to push dirty file data or metadata to disk for a remount is if we're remounting the filesystem read only, so this really could be moved to xfs_remount_ro. Once we've moved the call site, actually check the return value from sync_filesystem. Fixes: 02b9984d6408 ("fs: push sync_filesystem() down to the file system's remount_fs()") Signed-off-by: Darrick J.
