Subject: [PATCH 5/8] io_uring/net: io_async_msghdr caches for sendzc
Date: Thu, 8 Sep 2022 13:20:31 +0100 [thread overview]
Message-ID: <42fa615b6e0be25f47a685c35d7b5e4f1b03d348.1662639236.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
We already keep io_async_msghdr caches for normal send/recv requests,
use them also for zerocopy send.
