How? All I can see is that the fail path does
for (i = i - 1; i >= 0; i--)
so it will not do anything for i=0.

In the function memcg_init_list_lru
if call goto fail when i == 0, will cause out-of-bounds at lru->node[i]
The same out-of-bounds access scenario exists in the functions
memcg_update_list_lru and __memcg_init_list_lru_node
