From c54a1a06daa78613519b4d24495b0d175b8af63f Mon Sep 17 00:00:00 2001 From: "Masami Hiramatsu (Google)" Date: Sun, 18 Aug 2024 21:50:28 +0900 Subject: tracing: Fix function timing profiler to initialize hashtable Since the new fgraph requires to initialize fgraph_ops.ops.func_hash before calling register_ftrace_graph(), initialize it with default (tracing all functions) parameter.
