Subject: [PATCH v2 11/15] io_uring: move non aligned field to the end
Date: Thu, 24 Aug 2023 23:53:33 +0100 [thread overview]
Message-ID: <518e95d7888e9d481b2c5968dcf3f23db9ea47a5.1692916914.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.
