Well that should be already fixed by the following commits:

    dma-buf: try to replace a signaled fence in
reservation_object_add_shared_inplace

    The amdgpu issue to also need signaled fences in the reservation objects
should
    be fixed by now.

    Optimize the handling by replacing a signaled fence when adding a new
    shared one.

    dma-buf: keep only not signaled fence in
reservation_object_add_shared_replace v3

    The amdgpu issue to also need signaled fences in the reservation objects
    should be fixed by now.

    Optimize the list by keeping only the not signaled yet fences around.

    v2: temporary put the signaled fences at the end of the new container
    v3: put the old fence at the end of the new container as well.
