To be clear, the overflow occurs when we have more than (2^31)-1 blocks in the target. Disks themselves are often measured in base-10, but our blocks are base-2. So a 2 TB (2*10^12) file with 1 KiB (2^10) blocks might actually work, but just barely. Also a 2 TB file with something like 4K or larger block size will still work.
But yes -- we ought to increase those variables to 64 bits. I should have done that in the first place.
In precondition.cpp: The following line numbers and variable names need to change from int to int64_t: Line 39: outstandingIOs Line 419: postedIOs Line 420: completedIOs Line 428: TOTAL_BLOCKS
