We don't really know the state of req->extra{1,2] fields in
__io_fill_cqe_req(), if an opcode handler is not aware of CQE32 option,
it never sets them up properly. Track the state of those fields with a
request flag.
Fixes: 76c68fbf1a1f9 ("io_uring: enable CQE32")

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.
