Volume sizes can grow to a max of 16EiB on 64 bit systems.  Partition
sizes also have the same limit.

The quota size is still a signed 32 bit int IIRC.  So the max quota you
can set is 2TiB.  However, setting the quota to 0 or unlimited will
allow you to use any available space on the partition that volume is on.

I've seen 10TiB AFS partitions.  Things worked normally although the
output from fs lq does show some integers that have overflowed.
