      4  ***   This header was automatically generated from a Linux kernel header
      5  ***   of the same name, to make information necessary for userspace to
      6  ***   call into the kernel available to libc.  It contains only constants,
      7  ***   structures, and macros generated from the original header, and thus,
      8  ***   contains no copyrightable information.
      9  ***
     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
     13  ***
     14  ***   Any manual change here will be lost the next time this script will
     15  ***   be run. You've been warned!
