La causa principal es que se utilizó __kmalloc_cache_noprof directamente, lo que resultó en que no se asignara alloc_tag. Esto provocó que current->alloc_tag fuera nulo, lo que generó una advertencia en alloc_tag_add_check. Agreguemos una capa alloc_hook a __kmalloc_cache_noprof específicamente dentro de lib/slub_kunit.c, que es el único usuario de esta función slub interna fuera de la implementación de kmalloc en sí.
