| 4 | *** This header was automatically generated from a Linux kernel header |
| 5 | *** of the same name, to make information necessary for userspace to |
| 6 | *** call into the kernel available to libc. It contains only constants, |
| 7 | *** structures, and macros generated from the original header, and thus, |
| 8 | *** contains no copyrightable information. |
| 9 | *** |
| 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 |
| 13 | *** |
| 14 | *** Any manual change here will be lost the next time this script will |
| 15 | *** be run. You've been warned! |
