From 17b14d235f58155a05cd9371e4559361ca3c67da Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 19 Sep 2025 20:48:49 +0000 Subject: net: move sk_uid and sk_protocol to sock_read_tx sk_uid and sk_protocol are read from inet6_csk_route_socket() for each TCP transmit. Also read from udpv6_sendmsg(), udp_sendmsg() and others. Move them to sock_read_tx for better cache locality.
