Are you serious? What kind of application are you running?

OK, well hmm, then in 1969 we needed a volume size of 4K. Um, it's
probably more accurate to use 18 months as the doubling period.
Anyway, that's what the 64 bit option for buffer_head->b_blocknr is
supposed to handle. The question is, is it necessary to go to a
uniform 64 bit quantity for all users regardless of whether they feel
restricted by a 32 TB volume size limit or not.

OK, I looked again and saw the smiley. Sometimes it's hard to tell
what's outrageous when talking about disk sizes.
