parentbonding: Add a forgetten sysfs_attr_init on class_attr_bonding_masters (diff)
tcp: md5: dont write skb head in tcp_md5_hash_header()
tcp_md5_hash_header() writes into skb header a temporary zero value, this might confuse other users of this area. Since tcphdr is small (20 bytes), copy it in a temporary variable and make the change in the copy. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
