The reason for delaying my proposal for encl->refcount (which I will
post as RFC and won't merge it before getting screened from you) was
that I really focused making the most well thought comments to this.

Generally I think that we need to get your SRCU changes in before
anything in the form that the patch does not anything else but only
that. Without doing that comparing changes dealing with the life-cycle
of an enclave is way too much mind bending.
