Solve the following python programming problem given the following code:
def cache_control(**kwargs) : 
    def _cache_controller(viewfunc) : 
        def _cache_controlled(request, * args, **kw) : 
            response = viewfunc (request, * args, ** kw) 
            patch_cache_control (response, ** kwargs) 
            return response 
return wraps (viewfunc, assigned = available_attrs (viewfunc)) (_cache_controlled) 
return <MASK> 
    
    Given the code above, what is a proper replacement for <MASK>?
