I have been keeping an eye on this as well, and yes the issues are
getting fixed.
My current plan is to aim at getting v7 rebased onto -rc1 into a branch.
Review the changes very closely. Get some performance testing and some
other testing against it. Then to get this code into linux-next.
If everything goes smoothly I will send you a pull request next merge
window. I have no intention of shipping this (or sending you a pull
request) before it is ready.
