From e667152e0064acf1a308a1816719008e29bec76f Mon Sep 17 00:00:00 2001 From: "Masami Hiramatsu (Google)" Date: Thu, 2 Oct 2025 17:39:04 +0900 Subject: [PATCH] tracing: fprobe: Fix to init fprobe_ip_table earlier Since the fprobe_ip_table is used from module unloading in the failure path of load_module(), it must be initialized in the earlier timing than late_initcall(). Unless that, the fprobe_module_callback() will use an uninitialized spinlock of fprobe_ip_table. Initialize fprobe_ip_table in core_initcall which is the same timing as ftrace.
