as far as I can see it is completely nonsense what you try to do here.

The fence_drv references an amdgpu_userq object holds are the ones which the queue potentially waits on.

When the queue is freed up those references must be dropped, but that shouldn't affect fence_drv->fences in any way possible.

What exactly is the leak you are seeing?

Christian.
