Subject: [PATCH 06/11] xfrm: Use __skb_queue_tail in xfrm_trans_queue
Date: Thu, 11 Jan 2018 12:37:41 +0100 [thread overview]
Message-ID: <20180111113746.28186-7-steffen.klassert@secunet.com> (raw)
In-Reply-To: <20180111113746.28186-1-steffen.klassert@secunet.com>
From: Herbert Xu <herbert@gondor•apana.org.au>
We do not need locking in xfrm_trans_queue because it is designed
to use per-CPU buffers. However, the original code incorrectly
used skb_queue_tail which takes the lock. This patch switches
it to __skb_queue_tail instead.
