Merge tag 'io_uring-5.9-2020-08-28' of git://git.kernel.dk/linux-block

Pull io_uring fixes from Jens Axboe:
 "A few fixes in here, all based on reports and test cases from folks
  using it. Most of it is stable material as well:

   - Hashed work cancelation fix (Pavel)

   - poll wakeup signalfd fix

   - memlock accounting fix

   - nonblocking poll retry fix

   - ensure we never return -ERESTARTSYS for reads

   - ensure offset == -1 is consistent with preadv2() as documented

   - IOPOLL -EAGAIN handling fixes

   - remove useless task_work bounce for block based -EAGAIN retry"

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.
