I’ve addressed the comment by adding an explicit check to ensure the address is within MOD_INIT_TEXT or MOD_TEXT, and sent a new revision: [PATCH v2] arm64: ftrace: fix unreachable PLT for ftrace_caller in init_module with CONFIG_DYNAMIC_FTRACE Link: https://lore.kernel.org/all/20250905032236.3220885-1-panfan@qti.qualcomm.com/ # v2 Please let me know if anything else is needed. Best regards, Pan Fan
