[PATCHSET 0/2] io_uring tweaks for poll retry

[Jens Axboe <axboe@xxxxxxxxx>]

Just a few minor tweaks here:

- Base decision on whether we can support async EAGAIN try on a file on
  whether it has ->read_iter or ->write_iter, depending on direction.

- Only force punt to async worker for read/write if we can't poll for
  the retry.

Should go into 5.7.
