Message-ID: <20250723144927.507197150@kernel.org> Date: Wed, 23 Jul 2025 10:49:08 -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>, Yury Norov <yury.norov@...il.com> Subject: [for-next][PATCH 1/8] tracing: Replace opencoded cpumask_next_wrap() in move_to_next_cpu() From: Yury Norov <yury.norov@...il.com> The dedicated cpumask_next_wrap() is more verbose and effective than cpumask_next() followed by cpumask_first().
