Merge tag 'io_uring-5.5-2020-01-16' of git://git.kernel.dk/linux-block ...
Pull io_uring fixes form Jens Axboe:
- Ensure ->result is always set when IO is retried (Bijan)
- In conjunction with the above, fix a regression in polled IO issue
when retried (me/Bijan)
- Don't setup async context for read/write fixed, otherwise we may
wrongly map the iovec on retry (me)
- Cancel io-wq work if we fail getting mm reference (me)
- Ensure dependent work is always initialized correctly (me)
- Only allow original task to submit IO, don't allow it from a passed
ring fd (me)
