Macro Definition Documentation

dma_fence_array_for_each

#define dma_fence_array_for_each	(		fence,
			index,
			head
	)

Value:

    for (index = 0, fence = dma_fence_array_first(head); fence; \
         ++(index), fence = dma_fence_array_next(head, index))

dma_fence_array_for_each - iterate over all fences in array @fence: current fence @index: index into the array @head: potential dma_fence_array object

Test if @array is a dma_fence_array object and if yes iterate over all fences in the array. If not just iterate over the fence in @array itself.

For a deep dive iterator see dma_fence_unwrap_for_each().
