Subject: [PATCH 2/3] io_uring/net: canonise accept mshot handling
Date: Sun, 23 Feb 2025 17:22:30 +0000 [thread overview]
Message-ID: <daf5c0df7e2966deb0a115021c065fc6161a52d7.1740331076.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
Use a more recongnisable pattern for mshot accept, first try to post an
mshot cqe if needed and after do terminating handling.
