Hi guys,
while it is in most cases technically possible to not have a reference to the dma_fence when adding a callback it is usually a good idea to make sure to always have a reference anyway.
Otherwise we can indeed see cases where this doesn't really work as intended like for example in the now fixed EPOLL code.
