Hi Christian, Alex,

Sorry for the ping. No need to look at the patch itself.

I would just be grateful for a quick word on whether the issue it describes is a real one. If not, I will drop it; if it is, should I send a v2?

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?

Regards, Christian.

Thanks for your time, Junrui Luo
