Command to display skb_dst_set_noref manual in Linux: $ man 9 skb_dst_set_noref

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

skb

: buffer

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.
