RHEL 5.4 was just released, and it contains updates for ext4. 
It's called 'ext4' now, instead of 'ext4dev' earlier.

But it's still a tech preview.

See:
http://rhn.redhat.com/errata/RHSA-2009-1243.html (kernel changes/bugfixes)
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/html/Release_Notes/

http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/html/Release_Notes/Filesystems.html

"The ext4 file system (included in Red Hat Enterprise Linux as a
Technology Preview) has also been updated (BZ#485315)."

https://bugzilla.redhat.com/show_bug.cgi?id=485315

"The ext4 filesystem Technology Preview has been refreshed with updated
userspace tools"

"In previous versions of Red Hat Enterprise Linux utilizing the ext4
Technology Preview, ext4 filesystems were labeled as ext4dev. With this
update, ext4 filesystems are now tagged as ext4."

Hopefully that helps.
