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!
