Pull io_uring fixes from Jens Axboe:
"Fixes for the MSG_RING opcode. Nothing really major:
- Fix an overflow missing serialization around posting CQEs to the
target ring (me)
- Disable MSG_RING on a ring that isn't enabled yet. There's nothing
really wrong with allowing it, but 1) it's somewhat odd as nobody
can receive them yet, and 2) it means that using the right delivery
mechanism might change. As nobody should be sending CQEs to a ring
that isn't enabled yet, let's just disable it (Pavel)
- Tweak to when we decide to post remotely or not for MSG_RING
(Pavel)"

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.
