Hi everyone,

Since some operations can then lead to recursive handling nesting
dma_fence containers into each other is only allowed under some
restrictions.

dma_fence_array containers can be attached to dma_fence_chain
containers and dma_fence_chain containers by chaining them together.

In all other cases the individual fences should be extracted with
the appropriate iterators and added to the new containers
individually.

I've separated the i915 cleanup from this change since it is
generally a different functionality and the build bots complained
about some issues with those patches.

Most patches are already reviewd, but especially the first one still
needs an rb tag.

Please review and comment,
I see you dropped the i915 patch (probably due to lack of reviews?),
Got distracted with other things, but I'll see if I can resurrect that
and get it reviewed and merged.

I was about to send out the i915 patch when that one here is merged.

The CI systems yielded some strange error with that one and I wanted to double check what's that all about.

Christian.


Thanks,
