Merge tag 'for-6.7/io_uring-2023-10-30' of git://git.kernel.dk/linux

Pull io_uring updates from Jens Axboe:
 "This contains the core io_uring updates, of which there are not many,
  and adds support for using WAITID through io_uring and hence not
  needing to block on these kinds of events.

  Outside of that, tweaks to the legacy provided buffer handling and
  some cleanups related to cancelations for uring_cmd support"

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.
