There a few reasons why that hasn't been done, and none of them are related to the actual code/patches in there.. But I don't think it would help you. The io_uring branch is a mix of things that have gone into the current window (and may or may not need to go to stable), and things that are queued up for the next kernel versions (and aren't going to stable). This will just continue to drift from stable, until we respin a new kernel version internally. -- Jens Axboe
