Subject: [PATCH 11/16] io_uring: move non aligned field to the end
Date: Tue, 15 Aug 2023 18:31:40 +0100 [thread overview]
Message-ID: <be7d929fb23516cc5e5b759af9f72591590c2814.1692119257.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
Move not cache aligned fields down in io_ring_ctx, should change
anything, but makes further refactoring easier.
