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

+ *** 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!
