From 97b388d70b53fd7d286ac1b81e5a88bd6af98209 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 24 May 2022 15:21:00 -0600 Subject: 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.
