Koki Sanagi 07dc22e729 skb: Add tracepoints to freeing skb ... This patch adds tracepoint to consume_skb and add trace_kfree_skb before __kfree_skb in skb_free_datagram_locked and net_tx_action. Combinating with tracepoint on dev_hard_start_xmit, we can check how long it takes to free transmitted packets. And using it, we can calculate how many packets driver had at that time. It is useful when a drop of transmitted packet is a problem. sshd-6828 [000] 112689.258154: consume_skb: skbaddr=f2d99bb8 Signed-off-by: Koki Sanagi <sanagi.koki@jp.fujitsu.com> Acked-by: David S.
