Possible error on small_free_list::min_block_size

This method gives warning 'number_of_nodes': unreferenced formal parameter

memory/include/foonathan/memory/detail/small_free_list.hpp

Lines 63 to 68 in e9e13b0

    
           static constexpr std::size_t min_block_size(std::size_t node_size, 
        
                                                       std::size_t number_of_nodes) 
        
           { 
        
               return chunk_count(node_size) 
        
                      * (chunk_memory_offset + chunk_max_nodes * node_size); 
        
           }

This leads me to think that line 66 should use number_of_nodes instead of node_size

	static constexpr std::size_t min_block_size(std::size_t node_size,
	std::size_t number_of_nodes)
	{
	return chunk_count(node_size)
	* (chunk_memory_offset + chunk_max_nodes * node_size);
	}
