From 5ba8f4a39ecd160c7b6ef8ef1373375799710a97 Mon Sep 17 00:00:00 2001 From: Jiapeng Chong Date: Fri, 7 Mar 2025 10:14:12 +0800 Subject: [PATCH] function_graph: Remove the unused variable func MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Variable func is not effectively used, so delete it. kernel/trace/trace_functions_graph.c:925:16: warning: variable ‘func’ set but not used. This happened because the variable "func" which came from "call->func" was replaced by "ret_func" coming from "graph_ret->func" but "func" wasn't removed after the replacement.
