Move sync_filesystem() after sb_prepare_remount_readonly(). If writers sneak in anywhere from sync_filesystem() to sb_prepare_remount_readonly() it can cause inodes to be dirtied and writeback to occur well after sys_mount() has completely successfully. This was spotted by corrupted ubifs filesystems on reboot, but appears that it can cause issues with any filesystem using writeback.
