Subject: [PATCH net-next 0/3] tcp: rework tcp_v{4,6}_send_check()
Date: Tue,  3 Feb 2026 14:40:50 +0000	[thread overview]
Message-ID: <20260203144053.83193-1-edumazet@google.com> (raw)

tcp_v{4,6}_send_check() are only called from __tcp_transmit_skb()

They currently are in different files (tcp_ipv4.c and tcp_ipv6.c)
thus out of line.

This series move them close to their caller so that compiler
can inline them.

We save ~200 bytes of text with this series.

Eric Dumazet (3):
  tcp: inline __tcp_v4_send_check()
  tcp: move tcp_v6_send_check() to tcp_output.c
  tcp: make tcp_v{4,6}_send_check() static
