  20  * Before Linux 2.6.33 only O_DSYNC semantics were implemented, but using
  21  * the O_SYNC flag.  We continue to use the existing numerical value
  22  * for O_DSYNC semantics now, but using the correct symbolic name for it.
  23  * This new value is used to request true Posix O_SYNC semantics.  It is
  24  * defined in this strange way to make sure applications compiled against
  25  * new headers get at least O_DSYNC semantics on older kernels.
  26  *
  27  * This has the nice side-effect that we can simply test for O_DSYNC
  28  * wherever we do not care if O_DSYNC or O_SYNC is used.
  29  *
  30  * Note: __O_SYNC must never be used directly.
