The source code excerpts in my previous e-mail came from the latest Linux kernel (v4.7-rc3). Maybe older kernels behave in a different way.
BTW, did you run into the "swiotlb buffer is full" error messages while testing 4MB I/O? Have you already considered to reduce the memory that is needed for RDMA queues by reducing the queue depth? I ran my SRP tests with default swiotlb buffer size and with the following in srp_daemon.conf:
a queue_size=32,max_cmd_per_lun=32,max_sect=8192 Bart. -- 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
