Subject: [PATCH net-next 2/5] sched: don't use skb queue helpers
Date: Sun, 18 Sep 2016 00:57:31 +0200 [thread overview]
Message-ID: <1474153054-9059-3-git-send-email-fw@strlen.de> (raw)
In-Reply-To: <1474153054-9059-1-git-send-email-fw@strlen.de>
A followup change will replace the sk_buff_head in the qdisc
struct with a slightly different list.
Use of the sk_buff_head helpers will thus cause compiler
warnings.
Open-code these accesses in an extra change to ease review.
Signed-off-by: Florian Westphal <fw@strlen.de>
