the kernel while the vnode_if.h header is a bunch of inlines to call the code that is in the kernel. Generating the .h file on the fly is kinda bogus because it has to match the one compiled into the kernel. IMHO we should have kern/vnode_if.c and sys/vnode_if.h committed in the tree but that's another battle.
