 ***   This header was automatically generated from a Linux kernel header

 ***   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
