OK, refactored, cleaned up and force-pushed.  Current state:
Al Viro (7):
      keep io_event in aio_kiocb
      aio: store event at final iocb_put()
      Fix aio_poll() races
      make aio_read()/aio_write() return int
      move dropping ->ki_eventfd into iocb_destroy()
      deal with get_reqs_available() in aio_get_req() itself
      aio: move sanity checks and request allocation to io_submit_one()

Linus Torvalds (1):
      pin iocb through aio.
