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. -Chris
