From 9921d5013a6e51892623bf2f1c5b49eaecda55ac Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Thu, 27 Oct 2022 00:11:53 +0100 Subject: [PATCH] selftests/net: don't tests batched TCP io_uring zc 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.
