io_uring: handle completions in the core Normally request handlers complete requests themselves, if they don't return an error. For the latter case, the core will complete it for them. This is unhandy for pushing opcode handlers further out, as we don't want a bunch of inline completion code and we don't want to make the completion path slower than it is now. Let the core handle any completion, unless the handler explicitly asks us not to. Signed-off-by: Jens Axboe <axboe@kernel.dk> 2022-05-24 15:21:00 -06:00			`enum {`
