New Revision: 308454
URL: https://svnweb.freebsd.org/changeset/base/308454

Log:
  MFC: r307890
  mountd(8) was erroneously setting the sysctl for the old NFS server
  when the new/default NFS server was running, for the "-n" option.
  
  This patch fixes the problem for stable/10 and stable/9.
  Since the new NFS server uses vfs.nfsd.nfs_privport == 0 by default,
  there wouldn't have been many users affected by the code not setting
  it to 0 when the "-n" option was specified.
