+/**
+ * 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;
+ *
+ *		return 0;
+ *	}

+ *	static void kunit_kmalloc_free(struct kunit_resource *res)

+ *	{
+ *		struct kunit_kmalloc_params params;
+ *
+ *		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.
