Revision fc22579917eb7e13433448a342f1cb1592920940 authored by Eric Dumazet on 15 September 2017, 23:47:42 UTC, committed by David S. Miller on 16 September 2017, 16:07:01 UTC
Now skb->mstamp_skb is updated later, we also need to call tcp_rate_skb_sent() after the update is done. Fixes: 8c72c65b426b ("tcp: update skb->skb_mstamp more carefully") Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Soheil Hassas Yeganeh <soheil@google.com> Signed-off-by: David S.
