Interface additions to dma_fence_array?

Hi, Christian,

We have a use-case in i915 with async evictions where we'd like to use dma-fence-array in the following way

*Create in commit mode *Add context and seqno, *Publish (signaling critical section starts) *Add fence pointers to the arrary *Commit (signaling critical section ends, fence can now signal)

With a patch series I have, we use the i915 data structure dma_fence_work for this, but it'd be better to use dma_fence_array for various reasons. Would it be OK to add interfaces to dma-fence-array to facilitate this? Basic idea would be to defer the actions done by enable_signaling until commit is called.

Thanks, /Thomas
