VOP_LINK — create a new name for a file
VOP_LINK(struct vnode *dvp, struct vnode *vp, struct componentname *cnp);
This links a new name in the specified directory to an existing file.
Its arguments are:
dvp The vnode of the directory.
vp The vnode of the file to be linked.
cnp Pathname information about the file.
The pathname info should not be released on exit because it is done by
the caller. The directory and file vnodes should not be released on
VOP_LINK() expects the directory and file vnodes to be locked on entry
and will leave the vnodes locked on return.
Zero is returned if the file was linked successfully, otherwise an error
[EMLINK] The file has too many links.
[EPERM] The file is immutable.
[EXDEV] A hard link is not possible between different file
