		       union nfsctl_res	*resp);

DESCRIPTION
       Note: Since Linux 3.1, this system call no longer exists.

       /*
	* These	are the	commands understood by nfsctl().
	*/
       #define NFSCTL_SVC	   0	/* This	is a server process. */
       #define NFSCTL_ADDCLIENT	   1	/* Add an NFS client. */
       #define NFSCTL_DELCLIENT	   2	/* Remove an NFS client. */
       #define NFSCTL_EXPORT	   3	/* Export a filesystem.	*/
       #define NFSCTL_UNEXPORT	   4	/* Unexport a filesystem. */
       #define NFSCTL_UGIDUPDATE   5	/* Update a client's UID/GID map
					   (only in Linux 2.4.x	and earlier). */
       #define NFSCTL_GETFH	   6	/* Get a file handle (used by mountd)
					   (only in Linux 2.4.x	and earlier). */

       struct nfsctl_arg {
	   int			     ca_version;     /*	safeguard */
	   union {
	       struct nfsctl_svc     u_svc;
	       struct nfsctl_client  u_client;
	       struct nfsctl_export  u_export;
	       struct nfsctl_uidmap  u_umap;
	       struct nfsctl_fhparm  u_getfh;
	       unsigned	int	     u_debug;
	   } u;
       }

       union nfsctl_res	{
	       struct knfs_fh	       cr_getfh;
	       unsigned	int	       cr_debug;
       };
