Merge tag 'io_uring-5.5-20191226' of git://git.kernel.dk/linux-block
Pull io_uring fixes from Jens Axboe:
- Removal of now unused busy wqe list (Hillf)
- Add cond_resched() to io-wq work processing (Hillf)
- And then the series that I hinted at from last week, which removes
the sqe from the io_kiocb and keeps all sqe handling on the prep
side. This guarantees that an opcode can't do the wrong thing and
read the sqe more than once. This is unchanged from last week, no
issues have been observed with this in testing. Hence I really think
we should fold this into 5.5.
* tag 'io_uring-5.5-20191226' of git://git.kernel.dk/linux-block:
io-wq: add cond_resched() to worker thread
io-wq: remove unused busy list from io_sqe
io_uring: pass in 'sqe' to the prep handlers
io_uring: standardize the prep methods
io_uring: read 'count' for IORING_OP_TIMEOUT in prep handler
io_uring: move all prep state for IORING_OP_{SEND,RECV}_MGS to prep handler
io_uring: move all prep state for IORING_OP_CONNECT to prep handler
io_uring: add and use struct io_rw for read/writes
io_uring: use u64_to_user_ptr() consistently

+kunit_tool How-To
+=================
+
+What is kunit_tool?
+===================
+
+kunit_tool is a script (``tools/testing/kunit/kunit.py``) that aids in building
+the Linux kernel as UML (`User Mode Linux
+<http://user-mode-linux.sourceforge.net/>`_), running KUnit tests, parsing
+the test results and displaying them in a user friendly manner.
+
+What is a kunitconfig?
+======================
+
+It's just a defconfig that kunit_tool looks for in the base directory.
+kunit_tool uses it to generate a .config as you might expect. In addition, it
+verifies that the generated .config contains the CONFIG options in the
+kunitconfig; the reason it does this is so that it is easy to be sure that a
+CONFIG that enables a test actually ends up in the .config.
+
+How do I use kunit_tool?
+========================
+
+If a kunitconfig is present at the root directory, all you have to do is:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run
+
+However, you most likely want to use it with the following options:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all`
+
+- ``--timeout`` sets a maximum amount of time to allow tests to run.
+- ``--jobs`` sets the number of threads to use to build the kernel.
+
+If you just want to use the defconfig that ships with the kernel, you can
+append the ``--defconfig`` flag as well:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all` --defconfig
+
+.. note::
+ This command is particularly helpful for getting started because it
+ just works. No kunitconfig needs to be present.
+
+For a list of all the flags supported by kunit_tool, you can run:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --help
