54 | * Before Linux 2.6.33 only O_DSYNC semantics were implemented, but using |
55 | * the O_SYNC flag. We continue to use the existing numerical value |
56 | * for O_DSYNC semantics now, but using the correct symbolic name for it. |
57 | * This new value is used to request true Posix O_SYNC semantics. It is |
58 | * defined in this strange way to make sure applications compiled against |
59 | * new headers get at least O_DSYNC semantics on older kernels. |
60 | * |
61 | * This has the nice side-effect that we can simply test for O_DSYNC |
62 | * wherever we do not care if O_DSYNC or O_SYNC is used. |
63 | * |
64 | * Note: __O_SYNC must never be used directly. |
