This is the io_uring library, liburing. liburing provides helpers to setup and teardown io_uring instances, and also a simplified interface for applications that don't need (or want) to deal with the full kernel side implementation. For more info on io_uring, please see: https://kernel.dk/io_uring.pdf Subscribe to io-uring@vger.kernel.org for io_uring related discussions and development for both kernel and userspace.
