- ***
- ***   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!
