+ *** 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!
