Actually checking it's a fairly new feature (originally ext4 went off on its own for quite a while to avoid unsettling the older exts). It was added upstream a couple of years ago: commit 24b584240a0006ea7436cd35f5e8983eb76f1e6f Author: Theodore Ts'o <ty...@mit.edu> Date: Mon Dec 7 14:08:51 2009 -0500 ext4: Use ext4 file system driver for ext2/ext3 file system mounts And it was turned on in the Fedora kernels for f16: * Thu Jul 21 2011 Chuck Ebbert <cebb...@redhat.com> 3.0-0.rc7.git10.1 - - 3.0-rc7-git10 - - Use ext4 for ext2 and ext3 filesystems (CONFIG_EXT4_USE_FOR_EXT23=y) I'd not noticed it before as none of this gets built as modules now so you don't see the separate lsmod entries.
