I've found the cause of segmentation fault error. It related to  
gop_lookupname (which in turn calls lookupname) macro. I'm sure why  
but if I add lookupname declaration to all gop_loopkupname macro  
calling files and change gop_lookupname with lookupname function  
call, then it just works. Without this, the last argument (pointer to  
pointer of struct vnode) is not correctly transferred to lookupname  
function. I cannot find more elegant solution on this problem, yet.
