NAME

6       nfsservctl - syscall interface to kernel nfs daemon
7

LIBRARY

9       Standard C library (libc, -lc)
10

SYNOPSIS

12       #include <linux/nfsd/syscall.h>
13
14       long nfsservctl(int cmd, struct nfsctl_arg *argp,
15                       union nfsctl_res *resp);
16

DESCRIPTION

18       Note:  Since Linux 3.1, this system call no longer exists.  It has been
19       replaced by a set of files in the nfsd filesystem; see nfsd(7).
