Supporting an array or list of MRs seems pretty easy. If you ignore the weird fallback to physical DMA case when a MR fails case the SRP memory registration code isn't significanly more complex than that in iSER for example. And I think NFS needs the same support as well, as it allows using additional MRs when detecting a gap. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
