That's better, but not as flexible as the previously proposed approaches
that Sergey pointed you at:
http://lkml.iu.edu/hypermail/linux/kernel/1507.0/03233.html
http://lkml.iu.edu/hypermail/linux/kernel/1508.1/00696.html
There the operations are reachable via mapping, so we can support the
special operations migration also when mapping is otherwise needed; your
patch excludes mapping.
