They look fine to me. Ok, great. Although I have to admit I feel about uneasy about merging them for 5.2 unless Linus ends up doing an rc8. I plan to pull the prep_coherent patch into the dma-mapping tree as we'll need it as a prepation for other things as well, and then we can just have an immutable tree with the dma-iommu changes, so that it doesn't block other DMA mapping changes that will touch this code as well. > > -- > Catalin ---end quoted text---
