From c2dbaf0af05193fa69f267c37d1f825c1c3a59ab Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 12 Jun 2025 10:05:52 -0400 Subject: [PATCH] tracing: sched: Hide numa events under CONFIG_NUMA_BALANCING The events sched_move_numa, sched_stick_numa and sched_swap_numa are only called when CONFIG_NUMA_BALANCING is configured. As each event can take up to 5K of memory in text and meta data regardless if they are used or not, they should not be defined when unused. Move the #ifdef CONFIG_NUMA_BALANCING to hide these events as well.
