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