Hi all! We've been working on LTTng tracing for hns userspace provider recently, and we wonder why the DENABLE_LTTNG compiler option in rdma-core is disabled by default. If it's due to the concern about performance degradation, we have tested it on hns and found no significant performance difference when the tracepoints are disabled. Or is it because it introduces additional compilation dependency on LTTng library? Thanks, Junxian
