No, it's a good idea.  The big question is what we win with explicit
support in nvmet over just using the loop device.  I actually hacked
up support earlier and it didn't show any performance advantage.
That being said we now have the ITER_BVEC type and proper support
for in-kernel aio, so the code might become simple enough to just take
it.
