Subject: [PATCH v16 01/18] tracing: Use arch_ftrace_regs() for ftrace_regs_*() macros
Date: Tue, 15 Oct 2024 10:28:43 +0900	[thread overview]
Message-ID: <172895572290.107311.16057631001860177198.stgit@devnote2> (raw)
In-Reply-To: <172895571278.107311.14000164546881236558.stgit@devnote2>

From: Masami Hiramatsu (Google) <mhiramat@kernel.org>

Since the arch_ftrace_get_regs(fregs) is only valid when the
FL_SAVE_REGS is set, we need to use `&arch_ftrace_regs()->regs` for
ftrace_regs_*() APIs because those APIs are for ftrace_regs, not
complete pt_regs.
