The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script bellow. It has been compile tested. When memory is allocated, GFP_ATOMIC should be used to be consistent with the surrounding code. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> --- If needed, see post from Christoph Hellwig on the kernel-janitors ML: https://marc.info/?l=kernel-janitors&m=158745678307186&w=4 --- drivers/infiniband/hw/usnic/usnic_fwd.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/infiniband/hw/usnic/usnic_fwd.c b/drivers/infiniband/hw/usnic/usnic_fwd.c index 7875883621f4..398c4c00b932 100644 --- a/drivers/infiniband/hw/usnic/usnic_fwd.c +++ b/drivers/infiniband/hw/usnic/usnic_fwd.c @@ -214,7 +214,7 @@ usnic_fwd_alloc_flow(struct usnic_fwd_dev *ufdev, struct filter *filter, if (!flow) return ERR_PTR(-ENOMEM); - tlv = pci_alloc_consistent(pdev, tlv_size, &tlv_pa); + tlv = dma_alloc_coherent(&pdev->dev, tlv_size, &tlv_pa, GFP_ATOMIC); if (!tlv) { usnic_err("Failed to allocate memory\n"); status = -ENOMEM; @@ -258,7 +258,7 @@ usnic_fwd_alloc_flow(struct usnic_fwd_dev *ufdev, struct filter *filter, out_free_tlv: spin_unlock(&ufdev->lock); - pci_free_consistent(pdev, tlv_size, tlv, tlv_pa); + dma_free_coherent(&pdev->dev, tlv_size, tlv, tlv_pa); if (!status) return flow; out_free_flow: -- 2.25.1
