From: Eric Dumazet <edumazet@xxxxxxxxxx> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== [ Upstream commit 7cfd5fd5a9813f1430290d20c0fead9b4582a307 ] On 32bit arches, (skb->end - skb->data) is not 'unsigned int', so we shall use min_t() instead of min() to avoid a compiler error.
