Rather than have to make major changes to core infrastructure now,
let's work this out as a separate patchset to clean up the rmap and
reflink code in the next couple of releases. It's going to be better
to get working code out there now under the experimental tag than it
is is to keep it as an out of tree patchset for another cycle.

Cheers,

Dave.
