Where would the finalize() hook be called?

It is in the __bind function in drivers/md/dm.c, calling just before 
rcu_assign_pointer(md->map, (void *)t) which activates the inactive table.

 
That would be after the existing commit point, meaning the table swap
cannot be cancelled there, so is the finalize() you are proposing void()
i.e. designed so it always succeeds?
