  Relativistic hydrodynamics dual to Einstein-Gauss-Bonnet gravity in
asymptotic $\textrm{AdS}_5$ space is under study. To linear order in the
amplitude of the fluid velocity and temperature, we derive the fluid's
stress-energy tensor via an all-order resummation of the derivative terms. Each
order is accompanied by new transport coefficients, which all together could be
compactly absorbed into two functions of momenta, referred to as viscosity
functions. Via inverse Fourier transform, these viscosities appear as memory
functions in the constitutive relation between components of the stress-energy
tensor.
