XFS reflinks support

I'm looking to test xfs with reflink support (COW cloning).
The xfs updates made it into mainline kernel 4.6.0 and I believe the latest xfsprog 4.5.0 will enable it. I have both installed but I do not see the option -m reflink=1 in mkfs.xfs

Some overview of xfs's new party trick are here https://pkalever.wordpress.com/2016/01/ … -tutorial/

Re: XFS reflinks support

Answering my own question. reflink is available with xfs in kernal 4.9 or higher as an experimental feature. Link in my initial question shows how.
