[Intel-gfx] [PATCH] drm/i915/gt: Decouple obj<->fence reference cycles on freeing the GT pool

[Intel-gfx] [PATCH] drm/i915/gt: Decouple obj<->fence reference cycles on freeing the GT pool

[Chris Wilson]

Make sure that the obj->base.resv does not hold a reference to a fence
that itself has an active reference on the object. There is no automatic
pruning, so we must decouple such reference cycles (just in case they
exist) before discarding the pool->obj.

The active reference is pruned. I was thinking of other reference cycles
that may exist, but I do not think apply to the users of the buffer
pool. There is still an advantage here in that the pruning of that
reference may be delayed, so a kick here could release the memory
faster.
