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!
