Subject: [PATCH net-next] sky2: fix skb truesize underestimation
Date: Thu, 13 Oct 2011 23:11:30 +0200 [thread overview]
Message-ID: <1318540290.2533.22.camel@edumazet-laptop> (raw)
sky2 allocates a page per skb fragment. We must account
PAGE_SIZE increments on skb->truesize, not the actual frag length.
