*** 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.
