Merge tag 'io_uring-5.8-2020-06-11' of git://git.kernel.dk/linux-block

Pull io_uring fixes from Jens Axboe:
 "A few late stragglers in here. In particular:

   - Validate full range for provided buffers (Bijan)

   - Fix bad use of kfree() in buffer registration failure (Denis)

   - Don't allow close of ring itself, it's not fully safe. Making it
     fully safe would require making the system call more expensive,
     which isn't worth it.

   - Buffer selection fix

   - Regression fix for O_NONBLOCK retry

   - Make IORING_OP_ACCEPT honor O_NONBLOCK (Jiufei)

   - Restrict opcode handling for SQ/IOPOLL (Pavel)

   - io-wq work handling cleanups and improvements (Pavel, Xiaoguang)

   - IOPOLL race fix (Xiaoguang)"

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.
