0024  * Before Linux 2.6.33 only O_DSYNC semantics were implemented, but using
0025  * the O_SYNC flag.  We continue to use the existing numerical value
0026  * for O_DSYNC semantics now, but using the correct symbolic name for it.
0027  * This new value is used to request true Posix O_SYNC semantics.  It is
0028  * defined in this strange way to make sure applications compiled against
0029  * new headers get at least O_DSYNC semantics on older kernels.
