 * Containing struct
 *   |- Helper array

 *      [1] Helper item 1

 *          |- index (1)
 * To access the containing struct from one of the list_head items:
 * 1. Get the helper item from the list_head item using
 *    helper item =
 *        container_of(list_head item, helper struct type, list_head field)
 * 2. Get the contining struct from the helper item and its index in the array:
 *    containing struct =
