Hi Jason and Doug, Recently the ANSI T10 committee published the SRP2r04 draft. That document specifies how to support immediate data with the SRP protocol. As you know using immediate data reduces latency for small write requests. This patch series adds immediate data support to the SRP initiator and target drivers. Please consider this patch series for kernel v4.21. Thanks, Bart.
