I don't think so.  Doing it properly in-tree will mean that it is

  a) properly reviewed
  b) means we can do the major VM bits in the kernel without these
     really stupid exports

Have you looked at MOL recently?  It's more than disgusting.

And in addition to these issue we do of course as policy not add
random hooks in the kernel tree for out of tree stuff.  Especially
for hacks like this that don't even have the intention to get merged.
