Hi Mingming, Have you had a chance to start working on a design document, or at least an exploration of the possible design space for adding reflinks to ext4? It would be great if you could send out an e-mail with your initial thoughts so we can start discussing it on e-mail and on upcoming conference calls. Thanks!! - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
