Detailed Description
struct dma_resv_iter - current position into the dma_resv fences
Don't touch this directly in the driver, use the accessor function instead.
IMPORTANT
When using the lockless iterators like dma_resv_iter_next_unlocked() or dma_resv_for_each_fence_unlocked() beware that the iterator can be restarted. Code which accumulates statistics or similar needs to check for this with dma_resv_iter_is_restarted().
