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.
