By supporting modular tests we provide a simple way to do selective execution on a running system; specifying CONFIG_KUNIT=y CONFIG_KUNIT_EXAMPLE_TEST=m ...means we can simply "insmod example-test.ko" to run the tests. To achieve this we need to do the following: o export the required symbols in kunit o string-stream tests utilize non-exported symbols so for now we skip building them when CONFIG_KUNIT_TEST=m. o drivers/base/power/qos-test.c contains a few unexported interface references, namely freq_qos_read_value() and freq_constraints_init(). Both of these could be potentially defined as static inline functions in include/linux/pm_qos.h, but for now we simply avoid supporting module build for that test suite. o support a new way of declaring test suites. Because a module cannot do multiple late_initcall()s, we provide a kunit_test_suites() macro to declare multiple suites within the same module at once. o some test module names would have been too general ("test-test" and "example-test" for kunit tests, "inode-test" for ext4 tests); rename these as appropriate ("kunit-test", "kunit-example-test" and "ext4-inode-test" respectively). Also define kunit_test_suite() via kunit_test_suites() as callers in other trees may need the old definition.

This causes the Crypto API to be built-in whenever fscrypt is enabled. This makes it very difficult for me to test modular builds of the Crypto API without disabling fscrypt which is a pain. As fscrypt is still evolving and it's developing new ties with the fs layer, it's hard to build it as a module for now. However, the actual algorithms are not required until a filesystem is mounted. Therefore we can allow them to be built as modules.

Test data is derived from the table in the Inode Timestamps section of Documentation/filesystems/ext4/inodes.rst. KUnit tests run during boot and output the results to the debug log in TAP format (http://testanything.org/). Only useful for kernel devs running KUnit test harness and are not for inclusion into a production build.
