Merge tag 'io_uring-5.9-2020-08-21' of git://git.kernel.dk/linux-block

Pull io_uring fixes from Jens Axboe:

 - Make sure the head link cancelation includes async work

 - Get rid of kiocb_wait_page_queue_init(), makes no sense to have it as
   a separate function since you moved it into io_uring itself

 - io_import_iovec cleanups (Pavel, me)

 - Use system_unbound_wq for ring exit work, to avoid spawning tons of
   these if we have tons of rings exiting at the same time

 - Fix req->flags overflow flag manipulation (Pavel)

* tag 'io_uring-5.9-2020-08-21' of git://git.kernel.dk/linux-block:

  io_uring: fix racy req->flags modification
  io_uring: use system_unbound_wq for ring exit work
  io_uring: cleanup io_import_iovec() of pre-mapped request
  io_uring: get rid of kiocb_wait_page_queue_init()

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.
