|  ***   This header was automatically generated from a Linux kernel header
 | |
|  ***   of the same name, to make information necessary for userspace to
 | |
|  ***   call into the kernel available to libc.  It contains only constants,
 | |
|  ***   structures, and macros generated from the original header, and thus,
 | |
|  ***   contains no copyrightable information.
 | |
|  ***
 | |
|  ***   To edit the content of this header, modify the corresponding
 | |
|  ***   source file (e.g. under external/kernel-headers/original/) then
 | |
|  ***   run bionic/libc/kernel/tools/update_all.py
 | |
|  ***
 | |
|  ***   Any manual change here will be lost the next time this script will
 | |
|  ***   be run. You've been warned!
