| 7 | *** structures, and macros generated from the original header, and thus, |
| 8 | *** contains no copyrightable information. |

| 10 | *** To edit the content of this header, modify the corresponding |
| 11 | *** source file (e.g. under external/kernel-headers/original/) then |
| 12 | *** run bionic/libc/kernel/tools/update_all.py |
