This setting limits the maximum age of the running transaction to

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

If CONFIG_EXT2_FS is set to either 'y' (built-in) or 'm' (modular)
the corresponding obj- variable will be set, and kbuild will descend
down in the ext2 directory.
Kbuild only uses this information to decide that it needs to visit
the directory, it is the Makefile in the subdirectory that
specifies what is modular and what is built-in.
Kbuild uses this information not only to decide that it needs to visit
the directory, but also to decide whether or not to link objects from
the directory into vmlinux.
When Kbuild descends into the directory with 'y', all built-in objects
from that directory are combined into the built-in.a, which will be
eventually linked into vmlinux.
When Kbuild descends into the directory with 'm', in contrast, nothing
from that directory will be linked into vmlinux. If the Makefile in
that directory specifies obj-y, those objects will be left orphan.
It is very likely a bug of the Makefile or of dependencies in Kconfig.
It is good practice to use a `CONFIG_` variable when assigning directory
names. This allows kbuild to totally skip the directory if the
