        Don't check for double mounted file systems using the file system uuid.
        This is useful to mount LVM snapshot volumes.

-       Linux XFS behaves as if an "osyncisdsync" option is used,
-       which will make writes to files opened with the O_SYNC flag set
-       behave as if the O_DSYNC flag had been used instead.
-       This can result in better performance without compromising
-       data safety.
-       However if this option is not in effect, timestamp updates from
-       O_SYNC writes can be lost if the system crashes.
-       If timestamp updates are critical, use the osyncisosync option.
