Right.. What exactly is the end-user harm anyhow? Everything works 100% correctly without this patch, and your arguments all revolved around diagnostic capability.. It is a known weakness that the RDMA stack has crappy visibility. That has been talked about before. If you want better visibility then fix that by adding netlink stuff to dump out all the QP states, PDs, etc, similar to what TCP does.
