It`s a voltage-controlled voltage feedback for (very) low frequencies - in particular for dc (operating point stabilization).
Frequencies far above the lowpass corner frequency (set by the RC time constant) are not fed back.
During formulation of an answer I have detected an error in my first response. Sorry - it is voltage-controlled current feedback (sometimes called shunt-shunt feedback).
The output voltage drives a current into the the node at the gate where it is superimposed with the current driven by the signal voltage.
Both currents cause a voltage at the gate that controls the output current.
