Subject: [PATCH 4.19 56/79] net: use skb_queue_empty_lockless() in poll() handlers
Date: Fri, 8 Nov 2019 19:50:36 +0100 [thread overview]
Message-ID: <20191108174819.208207951@linuxfoundation.org> (raw)
In-Reply-To: <20191108174745.495640141@linuxfoundation.org>
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit 3ef7cf57c72f32f61e97f8fa401bc39ea1f1a5d4 ]
Many poll() handlers are lockless. Using skb_queue_empty_lockless()
instead of skb_queue_empty() is more appropriate.
