sync_file_ioctl_fence_info has a race between filling the status of the underlying fences and the overall status of the sync_file. If fence transitions in the time frame between its sync_fill_fence_info and the later dma_fence_is_signaled for the sync_file, the returned information is inconsistent showing non-signaled underlying fences but an overall signaled state. This patch changes sync_file_ioctl_fence_info to track what has been encoded and using that as the overall sync_file status.
