maxfiles is the real value; it's a loader tunable, and more importantly,
it can be modified at run time through the kern.maxfiles sysctl
variable. MAXFILES is simply the default value to which maxfiles is

Yes. If you use the MAXFILES option in your kernel config, config(8)
will add a corresponding #define MAXFILES to opt_param.h.
