Hold on a sec... This doesn't indicate that you made two opposite kinds
of change:

Here you added a type cast to suppress the warning that we're not
reporting large files properly. The warning provided a useful service to
us, pointing out a problem. Let's not hide it.
If we aren't ready to upgrade the reporting structure to handle large
sizes, at least we should set the reported size to some value that looks
(at least to a human) like a "can't represent the value" marker, such as
(-1) or the maximum value of the type.

... whereas here you fixed the code to be correct, which is great.
