First off, have you tested that this series actually works when merged with
the pending AIO changes from Kent? There a git tree with those pending
changes at git://git.kvack.org/~bcrl/aio-next.git , and they're in
linux-next.
One of the major problems your changeset continues to carry is that your
new read_iter/write_iter operations permit blocking (implicitely), which
really isn't what we want for aio. If you're going to introduce a new api,
it should be made non-blocking, and enforce that non-blocking requirement
(ie warn when read_iter/write_iter methods perform blockin operations,
similar to the warnings when scheduling in atomic mode). This means more
changes for some filesystem code involved, something that people have been
avoiding for years, but which really needs to be done.
