Define function as static inline in try-catch-impl.h to allow it to be used in kunit itself and tests.

/**
|
|
* struct kunit_try_catch - provides a generic way to run code which might fail.
|
|
* @test: The test case that is currently being executed.
|
|
* @try_completion: Completion that the control thread waits on while test runs.
|
|
* @try_result: Contains any errno obtained while running test case.
|
|
* @try: The function, the test case, to attempt to run.
|
|
* @catch: The function called if @try bails out.
|
|
* @context: used to pass user data to the try and catch functions.
|
|
*
|
|
* kunit_try_catch provides a generic, architecture independent way to execute
|
|
* an arbitrary function of type kunit_try_catch_func_t which may bail out by
|
|
* calling kunit_try_catch_throw(). If kunit_try_catch_throw() is called, @try
|
|
* is stopped at the site of invocation and @catch is called.
|
|
*
|
|
* struct kunit_try_catch provides a generic interface for the functionality
|
|
* needed to implement kunit->abort() which in turn is needed for implementing
|
|
* assertions. Assertions allow stating a precondition for a test simplifying
|
|
* how test cases are written and presented.
|
|
*
|
|
* Assertions are like expectations, except they abort (call
|
|
* kunit_try_catch_throw()) when the specified condition is not met. This is
|
|
* useful when you look at a test case as a logical statement about some piece
|
|
* of code, where assertions are the premises for the test case, and the
|
|
* conclusion is a set of predicates, rather expectations, that must all be
|
|
* true. If your premises are violated, it does not makes sense to continue.
