 * @rcu: used for releasing fence with kfree_rcu
 * @cb_list: list of all callbacks to call
 * @lock: spin_lock_irqsave used for locking
 * @context: execution context this fence belongs to, returned by
 *           dma_fence_context_alloc()
 * @seqno: the sequence number of this fence inside the execution context,
 * can be compared to decide which fence would be signaled later.
 * @flags: A mask of DMA_FENCE_FLAG_* defined below
 * @timestamp: Timestamp when the fence was signaled.
 * @error: Optional, only valid if < 0, must be set before calling
 * dma_fence_signal, indicates that the fence has completed with an error.
 *
 * the flags member must be manipulated and read using the appropriate
 * atomic ops (bit_*), so taking the spinlock will not be needed most
 * of the time.
 *
 * DMA_FENCE_FLAG_SIGNALED_BIT - fence is already signaled
 * DMA_FENCE_FLAG_TIMESTAMP_BIT - timestamp recorded for fence signaling
 * DMA_FENCE_FLAG_ENABLE_SIGNAL_BIT - enable_signaling might have been called
 * DMA_FENCE_FLAG_USER_BITS - start of the unused bits, can be used by the
 * implementer of the fence for its own purposes. Can be used in different
 * ways by different fence implementers, so do not rely on this.
 *
 * Since atomic bitops are used, this is not guaranteed to be the case.
 * Particularly, if the bit was set, but dma_fence_signal was called right
 * before this bit was set, it would have been able to set the
 * DMA_FENCE_FLAG_SIGNALED_BIT, before enable_signaling was called.
 * Adding a check for DMA_FENCE_FLAG_SIGNALED_BIT after setting
 * DMA_FENCE_FLAG_ENABLE_SIGNAL_BIT closes this race, and makes sure that
 * after dma_fence_signal was called, any enable_signaling call will have either
 * been completed, or never called at all.

	 * We clear the callback list on kref_put so that by the time we

	 * cb_list that they don't themselves hold a reference for.
	 *
	 * The lifetime of the timestamp is similarly tied to both the
	 * rcu freelist and the cb_list. The timestamp is only set upon
	 * signaling while simultaneously notifying the cb_list. Ergo, we
	 * only use either the cb_list of timestamp. Upon destruction,
	 * neither are accessible, and so we can use the rcu. This means
	 * that the cb_list is *only* valid until the signal bit is set,
	 * and to read either you *must* hold a reference to the fence,
