Subject: [PATCH v10 30/36] ftrace: Add CONFIG_HAVE_FTRACE_GRAPH_FUNC
Date: Tue, 7 May 2024 23:13:53 +0900 [thread overview]
Message-ID: <171509123327.162236.8914387678237087834.stgit@devnote2> (raw)
In-Reply-To: <171509088006.162236.7227326999861366050.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.
