Subject: [PATCH v4 22/33] tracing: Rename ftrace_regs_return_value to ftrace_regs_get_return_value
Date: Fri, 8 Dec 2023 19:28:42 +0900 [thread overview]
Message-ID: <170203132201.579004.3148503140553102819.stgit@devnote2> (raw)
In-Reply-To: <170203105427.579004.8033550792660734570.stgit@devnote2>
From: Masami Hiramatsu (Google) <mhiramat@kernel.org>
Rename ftrace_regs_return_value to ftrace_regs_get_return_value as same as
other ftrace_regs_get/set_* APIs.
