This set includes a sketch of how we might allow fences to be emitted directly within a batch buffer. This gets rid of the need for flushing around fence operations, which can be a win, and lets userspace more finely control things. If it looks reasonable, we could drop the separate ioctl and just use this instead... Alternately, I could still add the "return a fence from execbuf" behavior to the main execbuf ioctl, to represent completion for the whole thing. And per the last comments, we still want a way to pass an array of fences in with a given operation, so it can be properly ordered by the scheduler.
