Cuando se habilita el conjunto de CPU, en prepare_alloc_pages(), ac-\u0026gt;nodemask puede ser \u0026amp;current-\u0026gt;mems_allowed. Cuando se llama a first_zones_zonelist() para encontrar preference_zoneref, ac-\u0026gt;nodemask puede modificarse simult\u00e1neamente si la tarea se migra entre diferentes conjuntos de CPU. Suponiendo que tenemos 2 nodos NUMA, al recorrer el nodo 1 en ac-\u0026gt;zonelist, la m\u00e1scara de nodo es 2, y al recorrer el nodo 2 en ac-\u0026gt;zonelist, la m\u00e1scara de nodo es 1.
