    According to Eric Paris the clean/dirty state is only stored in
    memory. We could use the extended attribute interface as a way of not
    defining a new system call, or some other interface, but I'm not sure
    it's such a great match given that the extended attributes interface
    are designed for persistent data.

    I agree that doesn't actually work very well for the tracker use case,
    where you the clean/dirty bit to be persistent (in case the tracker is
    disabled due to the fact you are running on battery, for example, and
    then you reboot).
