20*4882a593Smuzhiyun  * Before Linux 2.6.33 only O_DSYNC semantics were implemented, but using
21*4882a593Smuzhiyun  * the O_SYNC flag.  We continue to use the existing numerical value
22*4882a593Smuzhiyun  * for O_DSYNC semantics now, but using the correct symbolic name for it.
23*4882a593Smuzhiyun  * This new value is used to request true Posix O_SYNC semantics.  It is
24*4882a593Smuzhiyun  * defined in this strange way to make sure applications compiled against
25*4882a593Smuzhiyun  * new headers get at least O_DSYNC semantics on older kernels.
26*4882a593Smuzhiyun  *
27*4882a593Smuzhiyun  * This has the nice side-effect that we can simply test for O_DSYNC
28*4882a593Smuzhiyun  * wherever we do not care if O_DSYNC or O_SYNC is used.
29*4882a593Smuzhiyun  *
30*4882a593Smuzhiyun  * Note: __O_SYNC must never be used directly.
