I saw the V2 patch, but the it will print the 32-bit truncated block
count, and it's possible if things are really insane, the number of
block groups calculated will be > 2**32. In which case the V1 patch
with the format string adjusted will print a less confusing message.
e.g.:

groups count too large: 8589934634 ....

as opposed to:

groups count too large: 42 ....
