I know its debugfs, but this feels a little loosey-goosey as an uAPI. Is there any expected format for the show function? What would other dmabuf heaps ideally export via this interface? Is there some consistent dma_heap-ish concept for it to justify it being under a dma_heap directory, and not just an independent debugfs file for the driver implementing the dmabuf heap? thanks -john
