From 1df4a945444f071a9c5e09580a485919c42d4de5 Mon Sep 17 00:00:00 2001 From: Breno Leitao Date: Wed, 16 Apr 2025 10:06:12 -0700 Subject: [PATCH] trace: tcp: Add const qualifier to skb parameter in tcp_probe event Change the tcp_probe tracepoint to accept a const struct sk_buff parameter instead of a non-const one. This improves type safety and better reflects that the skb is not modified within the tracepoint implementation.
