Subject: [PATCH v8 30/35] ftrace: Add CONFIG_HAVE_FTRACE_GRAPH_FUNC
Date: Mon, 26 Feb 2024 00:20:33 +0900 [thread overview]
Message-ID: <170887443285.564249.1101825677626621865.stgit@devnote2> (raw)
In-Reply-To: <170887410337.564249.6360118840946697039.stgit@devnote2>
From: Masami Hiramatsu (Google) <mhiramat@kernel.org>
Add CONFIG_HAVE_FTRACE_GRAPH_FUNC kconfig in addition to ftrace_graph_func
macro check. This is for the other feature (e.g. FPROBE) which requires to
access ftrace_regs from fgraph_ops::entryfunc() can avoid compiling if
the fgraph can not pass the valid ftrace_regs.
