Merge tag 'io_uring-5.14-2021-08-13' of git://git.kernel.dk/linux-block
Pull io_uring fixes from Jens Axboe:
"A bit bigger than the previous weeks, but mostly just a few stable
bound fixes. In detail:
- Followup fixes to patches from last week for io-wq, turns out they
weren't complete (Hao)
- Two lockdep reported fixes out of the RT camp (me)
- Sync the io_uring-cp example with liburing, as a few bug fixes
never made it to the kernel carried version (me)
- SQPOLL related TIF_NOTIFY_SIGNAL fix (Nadav)
- Use WRITE_ONCE() when writing sq flags (Nadav)
- io_rsrc_put_work() deadlock fix (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.
