7 ***   structures, and macros generated from the original header, and thus,
8 ***   contains no copyrightable information.

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

14 ***   Any manual change here will be lost the next time this script will
