CTERA has announced Next3 on Tuesday, see my blog post at: http://blog.ctera.com/2010/06/story-of-next3-and-thin-provisioned.html I wanted to thank you for helping me finalize the on-disk format in time for the announcement and I hope you will get around to reviewing the patches soon. Let me know if you want me to post the patches by email or if you want me to merge them with a difference branch. Cheers, Amir.
