Subject: [PATCH 17/19] io_uring: disable task plug for now
Date: Fri, 19 Aug 2022 23:27:36 +0800 [thread overview]
Message-ID: <20220819152738.1111255-18-hao.xu@linux.dev> (raw)
In-Reply-To: <20220819152738.1111255-1-hao.xu@linux.dev>
From: Hao Xu <howeyxu@tencent.com>
This is a temporary commit, the task plug causes hung and the reason is
unclear for now. So disable it in uringlet mode for now.
