Roman Penyaev 33e3960290 RDMA/rtrs-srv: fix SG mapping ... [ Upstream commit 83835f7c07 ] This fixes the following error on the server side: RTRS server session allocation failed: -EINVAL caused by the caller of the `ib_dma_map_sg()`, which does not expect less mapped entries, than requested, which is in the order of things and can be easily reproduced on the machine with enabled IOMMU. The fix is to treat any positive number of mapped sg entries as a successful mapping and cache DMA addresses by traversing modified SG table.
