So assuming it's the same bug, the use after free has moved from a 4096-byte slab to a 2048-byte slab. Were there ny data structures we shrank between 2.6.14 and 2.6.16? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
