io_uring maintainer Jens Axboe has posted an RFC patch set introducing a radical solution for handling blocking I/O operations within io_uring's 'never blocks' guarantee. The approach allows thread-identity switching so that slow blocking operations can be processed on different threads, improving performance over existing workarounds.
Background
io_uring is a Linux kernel subsystem for efficient asynchronous I/O, introduced in kernel 5.1. It has become the preferred I/O interface for high-performance applications due to its low overhead and scalable design.
