| * 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; |

| * 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. |
