  24  * for O_DSYNC semantics now, but using the correct symbolic name for it.
  25  * This new value is used to request true Posix O_SYNC semantics.  It is
  26  * defined in this strange way to make sure applications compiled against
  27  * new headers get at least O_DSYNC semantics on older kernels.
  28  *
  29  * This has the nice side-effect that we can simply test for O_DSYNC
  30  * wherever we do not care if O_DSYNC or O_SYNC is used.
