*** 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
