Subject: [PATCH for-6.1 1/1] selftests/net: don't tests batched TCP io_uring zc
Date: Thu, 27 Oct 2022 00:11:53 +0100	[thread overview]
Message-ID: <b547698d5938b1b1a898af1c260188d8546ded9a.1666700897.git.asml.silence@gmail.com> (raw)

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.
