io_uring
io_uring is a Linux kernel interface for providing submission and completion queue rings, which are shared between the kernel and userspace to avoid copies.[1] It has been primarily developed by Jens Axboe.
It was merged in kernel version 5.1.[2]
The liburing userspace library can be used to interact with the kernel interface.[1]
History
The Linux kernel had asynchronous I/O since version 2.5, but it was seen as difficult to use and inefficient.[3]
