From: Patricia Alfonso <trishalfonso@xxxxxxxxxx> Subject: kasan/kunit: add KUnit Struct to Current Task Patch series "KASAN-KUnit Integration", v14. This patchset contains everything needed to integrate KASAN and KUnit. KUnit will be able to: (1) Fail tests when an unexpected KASAN error occurs (2) Pass tests when an expected KASAN error occurs Convert KASAN tests to KUnit with the exception of copy_user_test because KUnit is unable to test those. Add documentation on how to run the KASAN tests with KUnit and what to expect when running these tests. This patch (of 5): In order to integrate debugging tools like KASAN into the KUnit framework, add KUnit struct to the current task to keep track of the current KUnit test.
