| 272 | + * such that it can replace the user-space addresses with appropriate | |
| 273 | + * DMA addresses or DMA addresses of a scatter gather list which is | |

| 278 | + * where it expects DMA addresses within the ASIV part of the DDCB and | |
| 279 | + * will check that against the ATS field definition. Any invalid or | |
