Hi Chris,
My concern with going in this direction was that we potentially allow
an application to allocate a lot of kernel memory but not a lot of fds
by creating lots of fences and then closing the fds but never
signaling them. Is that not an issue?

dma_fence_release() objects to a fence being freed before it is
signaled, so instead of playing fancy tricks to avoid handling dying
requests, let's keep the syncpt alive until signaled. This neatly
removes the issue with having to decouple the syncpt from the timeline
upon fence release.
