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.

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!
