The above is a bit detailed and may be inaccurate for some (pseudo) file

I'd tend to not define inode at all here, but if you prefer I'd just say
something generic like that "an inode is used to identify file system objects".

uintmax_t (as returned by fsusage)

uintmax_t as the threshold is limited to intmax_t, but size is not.

The main util under test is fine to print here

You're free to push with those adjustments.
