It met with some harsh resistance, so I backed off on it. Then Al Viro
got busy re-writing the iov_iter infrastructure and I put my patchset on
the shelf to look at later. Then Ming Lei submitted more up-to-date
patchset: https://lkml.org/lkml/2014/8/6/175

It looks like Ming is currently only pushing the first half of that
patchset. I don't know what his plans are for the last three patches:

aio: add aio_kernel_() interface
fd/direct-io: introduce should_dirty for kernel aio
block: loop: support to submit I/O via kernel aio based
