Thanks for the ack. Will fix all build issues in the next version.

Yes, ACTIVATE  / DECOMMISSION is one case that illustrates the need to
care about their internal relationship. And there is another case,
which is the serialization requirement between DF_FLUSH and
DEACTIVATE. This requires KVM to maintain an extra RWSEM. So I feel
that it would be good to hide these details away from KVM even if KVM
is the only user.

Thanks.
