The req_iterator just happens to have a similar fields to what the dma iterator needs, but we're not necessarily iterating a bio_vec here. Have the dma iterator define its private fields directly. It also helps to remove eyesores like "iter->iter.iter". Signed-off-by: Keith Busch <[email protected]> Reviewed-by: Christoph Hellwig <[email protected]>
This will make it easier to add different bvec sources, like for upcoming integrity support. It also makes iterating "special" payloads more common with iterating normal data bi_io_vecs. Signed-off-by: Keith Busch <[email protected]>
In preparing for integrity dma mappings, we can't rely on the request flag because data and metadata may have different mapping types. Signed-off-by: Keith Busch <[email protected]> Reviewed-by: Christoph Hellwig <[email protected]>
It's not serving any particular purpose anymore. pci_p2pdma_state() already has all the appropriate checks, so the flag isn't guarding anything. Signed-off-by: Keith Busch <[email protected]> Reviewed-by: Christoph Hellwig <[email protected]>
In preparing for dma mapping integrity metadata, move the common dma setup to a helper. Signed-off-by: Keith Busch <[email protected]> Reviewed-by: Christoph Hellwig <[email protected]>
Provide integrity metadata helpers equivalent to the data payload helpers for iterating a request for dma setup. Signed-off-by: Keith Busch <[email protected]>
Aligns data and metadata to the similar dma mapping scheme and removes one more user of the scatter-gather dma mapping. Signed-off-by: Keith Busch <[email protected]>
