This formalizes the checks KUnit maintainers have been running (or in other cases: forgetting to run). This script also runs them all in parallel to minimize friction (pytype can be fairly slow, but not slower than running kunit.py). Example output: $ ./tools/testing/kunit/run_checks.py Waiting on 4 checks (kunit_tool_test.py, kunit smoke test, pytype, mypy)... kunit_tool_test.py: PASSED mypy: PASSED pytype: PASSED kunit smoke test: PASSED On failure or timeout (5 minutes), it'll dump out the stdout/stderr. E.g. adding in a type-checking error: mypy: FAILED > kunit.py:54: error: Name 'nonexistent_function' is not defined > Found 1 error in 1 file (checked 8 source files) mypy and pytype are two Python type-checkers and must be installed. This file treats them as optional and will mark them as SKIPPED if not installed. This tool also runs `kunit.py run --kunitconfig=lib/kunit` to run KUnit's own KUnit tests and to verify KUnit kernel code and kunit.py play nicely together. It uses --build_dir=kunit_run_checks so as not to clobber the default build_dir, which helps make it faster by reducing the need to rebuild, esp. if you're been passing in --arch instead of using UML.

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.
