It's not too late to change things if necessary... it would be great if you could provide more of the feedback on this on the TC mailing list. > It would be great it you could reach out to the > wider storage community before taking bad ideas from the eMMC standard > and putting it into virtio. Noted. It would be great if we had more representation from the storage community ... meanwhile what would a good forum for this be? linux-block@vger.kernel.org ? Thanks, -- MST
