It is fine, but as a bare minimum, I would expect some sort of response, so I won't sit and wait for unknown date when this API will be acknowledged/NACKed. I would like to start to work on next step, e.g removing SG from RDMA, and I need to know if this foundation is stable to do so. > > No changs to dma-iommu.c are going to get merged without an explicit > ACK from Robin, and while there is no 100% for the core dma-mapping > code I will also not merge anything that hasn't been resolved with > my most trusted reviewer first, not even code I wrote myself. And do you know what is not resolved here? I don't. All technical questions/issues were handled. Thanks
