* 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)
* {
* kfree(res->data);
* }
*
* void *kunit_kmalloc(struct kunit *test, size_t size, gfp_t gfp)
* {
* 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.
