Arpitha Raghunandan fadb08e7c7 kunit: Support for Parameterized Testing 
Implementation of support for parameterized testing in KUnit. This
approach requires the creation of a test case using the
KUNIT_CASE_PARAM() macro that accepts a generator function as input.

This generator function should return the next parameter given the
previous parameter in parameterized tests. It also provides a macro to
generate common-case generators based on arrays. Generators may also
optionally provide a human-readable description of parameters, which is
displayed where available.

Note, currently the result of each parameter run is displayed in
diagnostic lines, and only the overall test case output summarizes
TAP-compliant success or failure of all parameter runs. In future, when
supported by kunit-tool, these can be turned into subsubtest outputs.

* struct kunit_resource - represents a *test managed resource*
* @data: for the user to store arbitrary data.
* @name: optional name
* @free: a user supplied function to free the resource. Populated by
* kunit_resource_alloc().
*
* Represents a *test managed resource*, a resource which will automatically be
* cleaned up at the end of a test case.
*
* Resources are reference counted so if a resource is retrieved via
* kunit_alloc_and_get_resource() or kunit_find_resource(), we need
* to call kunit_put_resource() to reduce the resource reference count
* when finished with it. Note that kunit_alloc_resource() does not require a
* kunit_resource_put() because it does not retrieve the resource itself.
*
* Example:
*
* .. code-block:: c
*
* struct kunit_kmalloc_params {
* size_t size;
* gfp_t gfp;
* };
*
* static int kunit_kmalloc_init(struct kunit_resource *res, void *context)
* {
* struct kunit_kmalloc_params *params = context;
* res->data = kmalloc(params->size, params->gfp);
*
* if (!res->data)
* return -ENOMEM;

*
* params.size = size;
* params.gfp = gfp;
*
* return kunit_alloc_resource(test, kunit_kmalloc_init,
* kunit_kmalloc_free, &params);
* }
*
* Resources can also be named, with lookup/removal done on a name
* basis also. kunit_add_named_resource(), kunit_find_named_resource()
* and kunit_destroy_named_resource(). Resource names must be
* unique within the test instance.

* which all the binary operators behave the same way as for the actual types
* (for example, there is no type that long long and unsigned long long can
* both be cast to where the comparison result is preserved for all values). So
* the best we can do is do the comparison in the original types and then coerce
* everything to long long for printing; this way, the comparison behaves
* correctly and the printed out value usually makes sense without
* interpretation, but can always be interpreted to figure out the actual
* value.
