From: Eric Biggers <ebiggers@xxxxxxxxxx>
When truncating a file to a size within the last allowed logical block,
block_to_path() is called with the *next* block. This exceeds the
limit, causing the "block %ld too big" error message to be printed.
This case isn't actually an error; there are just no more blocks past
that point. So, remove this error message.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
