Among many other projects I touched, we had a database engine which planned to move to io_uring as soon as it could be made available (it wasn't distributed outside company, so it was a question of internal infrastructure) PREEMPT_RT also includes a lot of possible low-latency work. io_uring also provides ridiculous performance benefits for normal server code, too.
