|  | ***   This header was automatically generated from a Linux kernel header | 
|  | ***   of the same name, to make information necessary for userspace to | 
|  | ***   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! |
