Dump of long lived i915_request object

I captured one of these long lived SLAB objects from my system using the crash
utility. I am not a graphics developer, but here is what stood out to me:

1. The dma_fence refcount is 1.
2. The dma_fence segno is 82576060.
3. The dma_fence ops is i915_fence_ops.
4. The global_seqno is 82576036.

I'll post my capture of the referenced intel_engine_cs next, although the
interesting thing there is that the timeline seqno is 82620551, which implies
that this particular object is old.
