core/device, a lot of it depends on when we'd exceed the nr_sge limit as well. But yes, it needs to move out ot the ULP and into the core, the ULP has no business here. As said a few times before we need a core API that takes a struct scatterlist and builds RDMA READ/WRITE requests from it in an efficient way. I have started talking to Sagi and preparing some build blocks for it, but getting all corner cases right will take a while. -- 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
