-	 *    then ignore it so can't get out.
-	 * 3. If this vnode is the root of a mounted

-	 *    vnode which was mounted on so we take the
-	 *    .. in the other filesystem.
-	 * 4. If the vnode is the top directory of
-	 *    the jail or chroot, don't let them out.
-	 * 5. If doing a capability lookup and lookup_cap_dotdot is
-	 *    enabled, return ENOTCAPABLE if the lookup would escape
-	 *    from the initial file descriptor directory.  Checks are
