40  * can be compared to decide which fence would be signaled later.
42  * @timestamp: Timestamp when the fence was signaled.
50  * DMA_FENCE_FLAG_SIGNALED_BIT - fence is already signaled
196 	 * @signaled:
198 	 * Peek whether the fence is signaled, as a fastpath optimization for
210 	bool (*signaled)(struct dma_fence *fence);  member
223 	 * interrupted, and remaining jiffies if fence has signaled, or 0 if wait

553  * Returns 0 if the fence has not yet been signaled, 1 if the fence has
