>Description:
	a file system(zfs-v13) NFS mounted now fails
	       fd = open(..., O_WRONLY|O_CREAT|O_EXCL, 0666);
	file is created with mode 0, and errno=Input/output errno(5).

>How-To-Repeat:
#include <stdio.h>
#include <fcntl.h>
#include <stdlib.h>
#include <string.h>
#include <errno.h>

main(int cc, char **vv)
{
     int	fd;
     char	*fn;

     if(cc > 1)
	  fn = vv[1];
     else
	  fn = "lock";
     fd = open(fn, O_WRONLY|O_CREAT|O_EXCL, 0666);
     if(fd < 0) {
	  int err = errno;
	  fprintf(stderr, "%d - %s\n", err, strerror(err));
     }
     exit(0);
