Module Compilation Error in vnode.h, missing vnode_if.h

[Can Sar]

Hi,

I am trying to compile a module for 6.0-RELEASE that includes  
vnode.h . Unfortunately even the simple test file below fails. It  
claims that sys/vnode_if.h is missing (which upon checking is true)  
and seems to be missing in general as well:
"http://fxr.watson.org/fxr/source/sys/vnode_if.h?v=RELENG60"
Any idea what I could be doing wrong?

Thank you very much for your help,
Can Sar

======================== ekm.c (my own testfile) =====================

#include <sys/param.h>
#include <sys/vnode.h>

int main() {
   struct vnode vp;
   struct vattr vap;
   struct ucred cred;

   VOP_GETATTR(&vp, &vap, &cred, NULL);
}

============================== Error ===============================
