Thanks for the summary! Since you mentioned MDS improvements, and just so it doesn't get lost: as you hinted at in off-list email, please do provide a write-up of CephFS features expected to work in Giant at the time of the release (broken down by kernel client vs. Ceph-FUSE, if necessary). Not in the sense that anyone is offering commercial support, but in the sense of "if you use this limited feature set, we are confident that it at least won't eat your data." I think that would be beneficial to a large portion of the user base, and clear up a lot of the present confusion about the maturity and stability of the filesystem.
