Merge tag 'for-5.4/io_uring-2019-09-24' of git://git.kernel.dk/linux-block

Pull more io_uring updates from Jens Axboe:
 "A collection of later fixes and additions, that weren't quite ready
  for pushing out with the initial pull request.

  This contains:

   - Fix potential use-after-free of shadow requests (Jackie)

   - Fix potential OOM crash in request allocation (Jackie)

   - kmalloc+memcpy -> kmemdup cleanup (Jackie)

   - Fix poll crash regression (me)

   - Fix SQ thread not being nice and giving up CPU for !PREEMPT (me)

   - Add support for timeouts, making it easier to do epoll_wait()
     conversions, for instance (me)

   - Ensure io_uring works without f_ops->read_iter() and
     f_ops->write_iter() (me)"
