Ah, very nice, I somehow missed it.
I guess one issue is that explicit sync isn't quite plumbed through compositors yet, so without Jason's DMA-BUF to sync_file IOCTL it'd be a bit difficult to use.
Can anybody set the deadline? I wonder if clients should be allowed to.
What happens if the deadline is exceeded? I'd assume nothing in particular, the deadline being just a hint?
