Correct, although it shouldn't be too much work for making it work on upstream

blktap3 is actively developed and is the I/O default data path in XenServer 
6.5. The repo you mention is the right one 
(https://github.com/xapi-project/blktap, git branch "xs64bit", but we'll soon 
bring the "master" branch up to date. I'd be more than happy to assist you and 
the developer in porting that patch to blktap3!
