>Description:
	I have mank a disk that has many (more than ten millions) hard links
	and /etc/periodic/weekly/310.locate makes this machine slow down
	extremely. The usage of vnode is as follows.

	kern.maxvnodes: 134882
	kern.minvnodes: 33720
	debug.numvnodes: 375907
	debug.wantfreevnodes: 25
	debug.freevnodes:  27046

	I think kern.maxvnodes should limit the debug.numvnodes.
