Subject: [PATCH AUTOSEL 6.0 09/44] selftests/net: don't tests batched TCP io_uring zc
Date: Fri, 18 Nov 2022 21:10:49 -0500 [thread overview]
Message-ID: <20221119021124.1773699-9-sashal@kernel.org> (raw)
In-Reply-To: <20221119021124.1773699-1-sashal@kernel.org>
From: Pavel Begunkov <asml.silence@gmail.com>
[ Upstream commit 9921d5013a6e51892623bf2f1c5b49eaecda55ac ]
It doesn't make sense batch submitting io_uring requests to a single TCP
socket without linking or some other kind of ordering. Moreover, it
causes spurious -EINTR fails due to interaction with task_work. Disable
it for now and keep queue depth=1.
