Controls the behavior of synchronous requests (e.g. fsync, O_DSYNC).
-\fBdefault\fR is the POSIX specified behavior of ensuring all synchronous
+\fBstandard\fR is the POSIX specified behavior of ensuring all synchronous
requests are written to stable storage and all devices are flushed to ensure
data is not cached by device controllers (this is the default). \fBalways\fR
causes every file system transaction to be written and flushed before its
