There is an improved implementation of trash in gerrit and can help get 
more traction with more reviews, rebases etc.

Don't think there are any major pieces missing to get rdma functional. 
More testing and bug fixes should be mostly it. Can happen in the 
interval between feature freeze and code freeze.

Update on a few other nice to have features that have either made the 
cut or can become available with some effort:

* glusterd volume locks - already in

* better logging - framework & few xlators have adopted this

* Exports Netgroups authentication - Needs some review attention and rebases

* Gluster user serviceable snapshots - feature already in

* rest-api - Early implementation available, need some more reviews

* Object Count & Archipelago - have some code, need a little more effort 
to make it available.

My inclination with respect to disperse/ec is to get it into the code 
base and mature it there (mostly from a performance perspective).

Better peer identification, trash and subset of the features in above 
lists can benefit by a few days extension. So it seems worthwhile for me 
to push out feature freeze till mid next week.
