From: Masami Hiramatsu (Google) Date: Thu, 2 Oct 2025 08:39:04 +0000 (+0900) Subject: tracing: fprobe: Fix to init fprobe_ip_table earlier X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e667152e0064acf1a308a1816719008e29bec76f;p=thirdparty%2Flinux.git 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.
