Right, that's another limit.  If we assume a filesystem with 8K blocks
and 1K frags, 2048=2^11 block numbers fit in a block.  The triple
indirect block thus points to 2^11 double indirect blocks, which point
to 2^22 single indirect blocks, which point to 2^33 data blocks of 2^13
bytes each, for a hard file size limit of 2^46 bytes.

Since this is bigger than the 2^41 byte filesystem size limit implied
by using 32-bit sector numbers and 512-byte sectors when talking to the
disk drivers, it is not a limit in practice.

Yup. :)
