I'm no NFS expert, but I did review draft-ietf-nfsv4-mv1-msns-update [0], which dealt with fixes in RFC5661 for multi-server namespace. This draft replaces that draft and obsoletes RFC5661 to incorporate changes documented in draft-ietf-nfsv4-mv1-msns-update. Almost all of the changes are to section 11 and 21. I briefly examined the changes in this draft and those noted in draft-ietf-nfsv4-mv1-msns-update, and it appears the changes are incorporated (I trust the authors faithfully made the changes). As far as the changes I suggested during my previous review [1], it appears as if the authors have: - major: 0-2 accepted and incorporated. The spirit of 3 was incorporated; makes it clear that AUTH_SYS provides "no provision to avoid modification of data in flight". - nits: incorporated 0-4, 6-8, and 10. I see the point to not making the changes suggested in 5 and 9.
