       nfsservctl - syscall interface to kernel nfs daemon


       long nfsservctl(int cmd, struct nfsctl_arg *argp,
		       union nfsctl_res *resp);

	* 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 file system. */
       #define NFSCTL_UNEXPORT	   4	/* unexport a file system. */
       #define NFSCTL_UGIDUPDATE   5	/* update a clients UID/GID map. */
       #define NFSCTL_GETFH	   6	/* get an fh (used by mountd) */

       struct nfsctl_arg {
	   int			     ca_version;     /* safeguard */
	   union {
	       struct nfsctl_svc     u_svc;

	       struct nfsctl_export  u_export;

       union nfsctl_res {
	       struct knfs_fh	       cr_getfh;
	       unsigned int	       cr_debug;

       On  success,  zero is returned.	On error, -1 is returned, and errno is
       set appropriately.

       This call is Linux-specific.
