Merge tag 'linux-kselftest-kunit-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull KUnit updates from Shuah Khan:
 "Several fixes and a new feature to support failure from dynamic
  analysis tools such as UBSAN and fake ops for testing.

   - a fake ops struct for testing a "free" function to complain if it
     was called with an invalid argument, or caught a double-free. Most
     return void and have no normal means of signalling failure (e.g.
     super_operations, iommu_ops, etc.)"
