* Before Linux 2.6.32 only O_DSYNC semantics were implemented, but using
|
|
* the O_SYNC flag. We continue to use the existing numerical value
|
|
* for O_DSYNC semantics now, but using the correct symbolic name for it.
|
|
* This new value is used to request true Posix O_SYNC semantics. It is
|
|
* defined in this strange way to make sure applications compiled against
|
|
* new headers get at least O_DSYNC semantics on older kernels.
|
|
*
|
|
* This has the nice side-effect that we can simply test for O_DSYNC
|
|
* wherever we do not care if O_DSYNC or O_SYNC is used.
|
|
*
|
|
* Note: __O_SYNC must never be used directly.
