   * the O_SYNC flag.  We continue to use the existing numerical value
   * for O_DSYNC semantics now, but using the correct symbolic name for it.
   * This new value is used to request true Posix O_SYNC semantics.  It is
   * defined in this strange way to make sure applications compiled against
   * new headers get at least O_DSYNC semantics on older kernels.
   *
   * This has the nice side-effect that we can simply test for O_DSYNC
   * wherever we do not care if O_DSYNC or O_SYNC is used.
   *
