Pull io_uring fixes from Jens Axboe:
- A single fix for over-eager retries for networking (Pavel)
- Revert the notification slot support for zerocopy sends.
It turns out that even after more than a year or development and
testing, there's not full agreement on whether just using plain
ordered notifications is Good Enough to avoid the complexity of using
the notifications slots. Because of that, we decided that it's best
left to a future final decision.
We can always bring back this feature, but we can't really change it
or remove it once we've released 6.0 with it enabled. The reverts
leave the usual CQE notifications as the primary interface for
knowing when data was sent, and when it was acked. (Pavel)
