Thank you, that is sensible, but have you actually verified that
attempting a lookup of a filename longer than 2.2 billion bytes causes
a problem? If that's the case, then your patch should be considered.
If not, it would seem to be a waste of time to worry about something
that cannot ever happen.

Kind regards,
Tigran
