> 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.
