   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.
