Re: [PATCH v3 01/25] dma-mapping: add generic helpers for mapping sgtable objects

From: Christoph Hellwig <hch@lst.de>
Date: 2020-05-05 10:22:39
Also in: linux-iommu, lkml

+static inline int dma_map_sgtable_attrs(struct device *dev,
+	struct sg_table *sgt, enum dma_data_direction dir, unsigned long attrs)
Two tab indents for parameter continuation, please.

Can we also skip the separate _attrs version?  The existing ones have the
separate _attrs variant as there were pre-existing versions without the
attrs argument and lots of users, but that doesn't really apply here as
an extra 0 argument isn't really an issue.
+static inline size_t iommu_map_sgtable(struct iommu_domain *domain,
+			unsigned long iova, struct sg_table *sgt, int prot)
+{
+	return iommu_map_sg(domain, iova, sgt->sgl, sgt->orig_nents, prot);
+}
Should this be a separate patch due to the different subsystems?

FYI, I'll happily pick up the prep patches in an immutable branch of
the dma-mapping tree one we have settled on the details.
