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