Jason, Recently the code in rxe_reg_user_mr was changed to check if the driver supported the access flags. Since the rxe driver does nothing about relaxed ordering. I assumed that the driver didn't support that option but it turns out that this breaks the perf tests which request relaxed ordering by default. It looks like the correct fix for this is to go ahead and claim support for relaxed ordering but it will be a no-op. Thoughts? Bob
