Subject[PATCH v4 4/4] kunit: example: Provide example exit functions
From
Add an example .exit and .suite_exit function to the KUnit example
suite. Given exit functions are a bit more subtle than init functions
(due to running in a different kthread, and running even after tests or
test init functions fail), providing an easy place to experiment with
them is useful.
