Probably 2.4.11 is the right one.

Journaling filesystems need a special interface, but reiserfs, ext3, and
XFS all support this interface.  For non-journaled filesystems, it will
just sync the device, but this is not 100% guaranteed to make the fs
consistent.  Also, when you mount an ext2 filesystem it will report the
filesystem as dirty, but it will still mount, unlike ext3.
