[Linaro-mm-sig] [PATCH 0/3] dma-buf: Check status of enable-signaling bit on debug

Fence signaling must be enabled to make sure that the dma_fence_is_signaled() and dma_fence_is_signaled_locked() function ever returns true. Since drivers and implementations sometimes mess this up, this ensures correct behaviour when DEBUG_WW_MUTEX_SLOWPATH is used during debugging. This should make any implementation bugs resulting in not signaled fences much more obvious.
