The parameters I suspect it to have are (dev_t device, ino_t node, 
uint32 flags, port_id port, int32 handlerToken, bool preferredHandler). 
Their order is subject of speculation on my part. 
_kstop_watching_vnode_() should have three parameters, being similar to 
the last ones of _kstart_watching_vnode_().
