Name
skb_dst_set_noref —
sets skb dst, hopefully, without taking reference
Synopsis
void skb_dst_set_noref ( | struct sk_buff * skb, |
| | struct dst_entry * dst); |
Arguments
struct sk_buff * skb
buffer
struct dst_entry * dst
dst entry
Description
Sets skb dst, assuming a reference was not taken on dst.
If dst entry is cached, we do not take reference and dst_release
will be avoided by refdst_drop. If dst entry is not cached, we take
reference, so that last dst_release can destroy the dst immediately.
