The sysctl(2) manpage also lists the corresponding sysctl(8) variables:
Information may be retrieved and set using the sysctl(8) utility;
the variable names used by this utility are given here in parentheses.
Among these is kern.file, which, understandably, just points to fstat(8).
Would it be better to not list it as a sysctl(8) var?
Or is it left there on purpose?
