37  * This structure defines a generic sync object which wraps a &dma_fence.
41 	 * @refcount: Reference count of this object.

73  * drm_syncobj_get - acquire a syncobj reference
74  * @obj: sync object
76  * This acquires an additional reference to @obj. It is illegal to call this
77  * without already holding a reference. No locks required.

97  * @syncobj: sync object.
99  * This acquires additional reference to &drm_syncobj.fence contained in @obj,
100  * if not NULL. It is illegal to call this without already holding a reference.
