The corrent ordering is deliberate; it allows file systems that have ext2 and ext3 only file system features will be reported as using ext2 and ext3 in /proc/mounts. This doesn't matter quite as much, but it could potentially break userspace if a legacy file system that only has ext2 file system features is mounted and reported as ext4. So sorry, I can't take this change. - Ted
