NAME

gnet_stats_start_copy_compat - start dumping procedure in compatibility mode

SYNOPSIS

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, int padattr);

ARGUMENTS

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

padattr

padding attribute

DESCRIPTION

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.
