Subject: [PATCH 2/5] skbuff: skb_segment: s/skb_frag/frag/
Date: Mon, 10 Mar 2014 18:29:14 +0200 [thread overview]
Message-ID: <1394468807-25980-3-git-send-email-mst@redhat.com> (raw)
In-Reply-To: <1394468807-25980-1-git-send-email-mst@redhat.com>
skb_frag can in fact point at either skb
or fskb so rename it generally "frag".
