I am targeting a problem about RoCE and SCSI over RDMA from srpt in kernel-4.14. When insmod srpt.ko and insmod hns-roce-hw-v2.ko, it will

How about the following patch?

No, I did not find this patch in the latest kernel-5.3 or others.
What I meant is: can you try that patch?

if we don't add the patch (IB/srpt: Add RDMA/CM support) and only merge your patch, it will not resolve our question.

if we add the patch(IB/srpt: Add RDMA/CM support) and merge your patch, it will success.

Did you apply my patch on top of kernel v4.14 or on top of a more recent kernel version?

Thanks,

Bart.
