I believe Saurabh had a follow-up discussion in person with Christoph regarding this patch, following our talk on this topic at LPC: https://lpc.events/event/18/contributions/1817/ @Christoph, would you mind giving your Ack if this patch v2 looks good to you, or kindly point out if there are any lingering concerns?
