[CentOS] centos6 filesystem size limit

I just read the rhel6 filesystem size limit.


It says 16TB limit for ext4 (same as ext3)?!?!  I thought ext4 was
supposed to support 1EB ( ~ 1 million TB) limit. That was one of the
main advantages of rhel6. After a little more digging all I found was
that the user space formatting tools (mkfs.ext4) only support 32bit
filesystems (not 48bits). I'm surprised about this, I thought people
would be waiting for >16TB support in rhel6. Does anyone know if this
is going to change in point releases of rhel/centos6?

Happy New Year
