From e68849097e82f7e42f3212cefbdcb7d1428e6ffd Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 12 Jun 2025 10:53:13 -0400 Subject: [PATCH] PM: tracing: Hide device_pm_callback events under PM_SLEEP The events device_pm_callback_start and device_pm_callback_end events are only called when CONFIG_PM_SLEEP is defined. As each event can take up to 5K regardless if they are used or not, it's best not to define them when they are not used. Add #ifdef around these events when they are not used.
