Most of the sysctls can be viewed with sysctl(8), and most of the
rest are helpful when you try to display them.  In this case:

	thoreau:~ 1> sysctl kern.vnode                                          
	sysctl: Use pstat to view kern.vnode information
	thoreau:~ 2> man pstat
	...
	     -v      Print the active vnodes.  [ ... ]
	thoreau:~ 3> pstat -v
	1995 active vnodes
	*** MOUNT ffs /dev/raid0a on / (local,rootfs)
	ADDR     TYP VFLAG  USE HOLD TAG FILEID IFLAG RDEV|SZ
	fffffc0006a39448 chr     -    1    0   1 240822     -    drum
	fffffc0004f43030 chr     -    1    0   1 240823     A    kmem
	fffffc0006463750 chr     -    1    0   1 240824     -     mem
	[ ... ]

Look in /usr/src/usr.sbin/pstat/pstat.c for details of how this is done.
