That may be true, however, putting it into the Xen tree at the moment
would only be temporary anyway.  I think that it changing shape while
in the Xen tree isn't likely to break anything, as people using it
at that point would have to know that it was subject to change.  I
don't think there is any danger in anyone snapshotting the Xen tree
with a not-yet-final version of dm-userspace in it and assuming it's
production-ready.

To quote your quote:

The code has been accepted into the device-mapper review tree, which
may qualify it as almost "ready to go upstream".  So, if we fall under
that umbrella, I think it's reasonable to get it into the Xen tree for
testing and review.  Perhaps Chris can weigh in here?
