[CentOS] ext4 in centos 5.3

Hi,

Recently I build a filesystem in a device using mkfs.ext4 but when I
tried to mount the device show this error:

    mount: unknown filesystem type 'ext4'

But when I build the same device with mkfs.ext4dev I can mont the
device without problem.

My doubt is when Centos 5.4 is released if I will have a problem
because the partition is ext4dev.


Thanks,
