Subject: [RFC PATCH 16/17] vsock: Remove unused used length
Date: Mon, 17 May 2021 17:08:35 +0800 [thread overview]
Message-ID: <20210517090836.533-17-xieyongji@bytedance.com> (raw)
In-Reply-To: <20210517090836.533-1-xieyongji@bytedance.com>
The used length is not used in some cases. Let's drop it
and pass NULL to virtqueue_get_buf() instead.
