Preheat oven to 350.  Pour cherry pie filling into the bottom of 8x8 or 9x13 pan.

Combine flour, oatmeal, brown sugar, cinnamon, salt, and butter. Mix with a pastry cutter until crumbly. Sprinkle mixture over the cherry filling evenly. Bake for 20 minutes or until topping is browned and filling is bubbling.
