2^31 x 512 = 1TB (negative block numbers are 'special'). Not really
a bug. Though I seem to recall a year or two ago someone had created
a much larger partition, I'm not quite sure how it could have worked.
As far as I understand the system we convert a block numbers to 512 byte
blocks at the device layer so even FFS filesystems w/ large block sizes
wouldn't be sufficient to get past the kernel limitation.
We just have to convert everything to 64 bit offsets all the way
through, especially with 500GB+ drives coming to market probably this
year sometime.
