76b7e005 | 22 | * Before Linux 2.6.33 only O_DSYNC semantics were implemented, but using |
6b2f3d1f CH |
23 | * the O_SYNC flag. We continue to use the existing numerical value |
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. | |
31 | * | |
32 | * Note: __O_SYNC must never be used directly. | |
