Message-ID: <20250930170302.206716475@kernel.org> Date: Tue, 30 Sep 2025 13:01:41 -0400 From: Steven Rostedt <rostedt@...nel.org> To: linux-kernel@...r.kernel.org Cc: Masami Hiramatsu <mhiramat@...nel.org>, Mark Rutland <mark.rutland@....com>, Mathieu Desnoyers <mathieu.desnoyers@...icios.com>, Andrew Morton <akpm@...ux-foundation.org>, Liao Yuanhong <liaoyuanhong@...o.com> Subject: [for-next][PATCH 06/11] tracing: Remove redundant 0 value initialization From: Liao Yuanhong <liaoyuanhong@...o.com> The saved_cmdlines_buffer struct is already zeroed by memset(). It's redundant to initialize s->cmdline_idx to 0.
