  The irreversible currents and entropy production rate of a dilute colloidal
suspension are calculated using the linear irreversible thermodynamics and the
linear response theory. The \anomalous" or \hidden" entropy recently discussed
in the context of the stochastic thermodynamics is fully accounted in these
classic frameworks. We show that the two distinct formulations lead to
identical results as long as the local equilibrium assumption or, equivalently
the linear response theory, is valid.
