Aleksa Sarai 9a0584f056 selftests: openat2: fix build error on newer glibc
It appears that newer glibcs check that openat(O_CREAT) was provided a
fourth argument (rather than passing garbage), resulting in the
following build error:

> In file included from /usr/include/fcntl.h:301,
>                  from helpers.c:9:
> In function 'openat',
>     inlined from 'touchat' at helpers.c:49:11:
> /usr/include/x86_64-linux-gnu/bits/fcntl2.h:126:4: error: call to
> '__openat_missing_mode' declared with attribute error: openat with O_CREAT
> or O_TMPFILE in third argument needs 4 arguments
>   126 |    __openat_missing_mode ();
>       |    ^~~~~~~~~~~~~~~~~~~~~~~~

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
