- The address of a variable where the resulting locked vnode should be stored.
- Fa cnp
- The pathname component created.
- Fa vap
- The attributes that the new object should be created with.
- Fa target
- The pathname of the target of the symlink.
These entry points are called after VOP_LOOKUP9 when an object is being created.
