It is defined in vnode_if.h, generated as part of the kernel build 
process.
The source file is sys/kern/vnode_if.src, and look at 
sys/tools/vnode_if.awk and sys/conf/kmod.mk for how it is used.

Once again, attempting to use kernel internals outside of the supported 
interfaces is just asking for trouble; I do not understand why this 
message is not sinking in over the course of your previous mails to these 
lists, so I will not try to belabor it further.
