It should have been named appropriately to avoid confusion. Later, when we actually understand what other IOMMUs need, we can evolve the specific API for generic purposes. Then we can rename the API to more generic. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
