*** This header was automatically generated from a Linux kernel header

|

|
|
*** 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
