Basically whenever the upstream target layer maintainer comes back from
wherever he is. I know that answer sucks, and I am sorry. All I can do
is ping him every once in a while, resend my patches to keep them up to
date, and wait for him to get time.

When the target layer maintainer at least says that the kernel/user API
being added in this patchset

https://www.spinics.net/lists/target-devel/msg16372.html

is ok, I have a kernel that I can push to

https://github.com/ceph/ceph-client

with everything needed so you do not have to wait for them.

A updated tcmu-runner rpm will also needed, but I am the maintainer and
that is just waiting for the kernel patches to get the OK.
