Oh, and while we're at it. Can someone explain why we're even using rdma_read_chunk_frmr for IB? It seems to work around the fact tat iWarp only allow a single RDMA READ SGE, but it's used whenever the device has IB_DEVICE_MEM_MGT_EXTENSIONS, which seems wrong.
I think Steve can answer it better than I can. I think that it is just to have a single code path for both IB and iWARP. I agree that the condition seems wrong and for small transfers rdma_read_chunk_frmr is really a performance loss. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
