gnet_stats_start_copy_compat - start dumping procedure in compatibility mode

int gnet_stats_start_copy_compat(struct sk_buff *  skb , int  type , int  tc_stats_type , int  xstats_type , spinlock_t *  lock , struct gnet_dump *  d );

skb
    socket buffer to put statistics TLVs into

type
    TLV type for top level statistic TLV

tc_stats_type
    TLV type for backward compatibility struct tc_stats TLV

xstats_type
    TLV type for backward compatibility xstats TLV

lock
    statistics lock

d
    dumping handle

Initializes the dumping handle, grabs the statistic lock and appends an empty TLV header to the socket buffer for use a container for all other statistic TLVS.

The dumping handle is marked to be in backward compatibility mode telling all gnet_stats_copy_XXX functions to fill a local copy of struct tc_stats.

Returns 0 on success or -1 if the room in the socket buffer was not sufficient.
