Bug description:
  for example version "3.0" break mount.nfs, because this code catch
  segfault on "3.0"

  static inline unsigned int linux_version_code(void)
  {
  	struct utsname my_utsname;
  	unsigned int p, q, r;

  	if (uname(&my_utsname))
  		return 0;

  	p = atoi(strtok(my_utsname.release, "."));
  	q = atoi(strtok(NULL, "."));
  	r = atoi(strtok(NULL, "."));
  	return MAKE_VERSION(p, q, r);
  }

  and this is very common hack, linux version always starts with three
  numbers.
