Subject: [PATCH net-next 0/4] tcp_metrics: four fixes

Looking at an inconclusive syzbot report, I was surprised
to see that tcp_metrics cache on my host was full of
useless entries, even though I have
/proc/sys/net/ipv4/tcp_no_metrics_save set to 1.

While looking more closely I found a total of four issues.

Eric Dumazet (4):
  tcp_metrics: add missing barriers on delete
  tcp_metrics: properly set tp->snd_ssthresh in tcp_init_metrics()
  tcp_metrics: do not create an entry from tcp_init_metrics()
  tcp_metrics: optimize tcp_metrics_flush_all()
