Subject: [PATCH net-next 0/5] tcp: move some fastpath fields to appropriate groups
Date: Thu, 30 Apr 2026 10:00:16 +0000 [thread overview]
Message-ID: <20260430100021.211139-1-edumazet@google.com> (raw)
Move following fields to better groups to increase data locality.
- delivered
- delivered_ce
- segs_in
- segs_out
- first_tx_mstamp
- delivered_mstamp
- max_packets_out
- cwnd_usage_seq
- rate_delivered
- rate_interval_us
No change in overall tcp_sock size.
Eric Dumazet (5):
tcp: move tp->delivered and tp->delivered_ce to tcp_sock_write_tx
group
tcp: move tp->segs_in and tp->segs_out to tcp_sock_write_txrx group
tcp: move tp->first_tx_mstamp and tp->delivered_mstamp to
tcp_sock_write_tx
tcp: move tp->bytes_acked to tcp_sock_write_tx group
tcp: move max_packets_out, cwnd_usage_seq, rate_delivered and
rate_interval_us to tcp_sock_write_tx group
