ext4 volume > 16TB possible?

Hi Folks,

Is there as of yet a means of creating a large ext4 filesystem?  mke2fs
as of 1.40.8 is still limited to creating ext3 filesystems at 16TB.

Disk /dev/sda: 22.0TB
Sector size (logical/physical): 512B/512B

mke2fs 1.40.8 (13-Mar-2008)
mke2fs: File too large while trying to determine filesystem size

Support for 64-bit block number is not yet available on e2fsprogs.  It
is being worked on but other features currently have higher priority
that this so its hard to say when it will be done.

OK - I am happy to test when this feature is merged.

Thanks,
