The io_uring subsystem is more than an asynchronous I/O interface for Linux; it is, for all practical purposes, an independent system-call API. It has enabled high-performance applications, but it also brings challenges for code built around classic, Unix-style system calls. For example, the seccomp() sandboxing mechanism does not work with it, causing applications using seccomp() to disable io_uring outright. Io_uring maintainer Jens Axboe is seeking to improve that situation with a rapidly evolving patch series adding a new restrictive mechanism to that subsystem.
