Merge tag 'linux-kselftest-5.5-rc1-kunit' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest
Pull kselftest KUnit support gtom Shuah Khan:
"This adds KUnit, a lightweight unit testing and mocking framework for
the Linux kernel from Brendan Higgins.
KUnit is not an end-to-end testing framework. It is currently
supported on UML and sub-systems can write unit tests and run them in
UML env. KUnit documentation is included in this update.
In addition, this Kunit update adds 3 new kunit tests:
- proc sysctl test from Iurii Zaikin
- the 'list' doubly linked list test from David Gow
- ext4 tests for decoding extended timestamps from Iurii Zaikin
In the future KUnit will be linked to Kselftest framework to provide a
way to trigger KUnit tests from user-space"
