From a3b366dbf468788baa2e0ccdccd8482ac277e47b Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 12 Jun 2025 09:49:32 -0400 Subject: [PATCH] tracing, AER: Hide PCIe AER event when PCIEAER is not configured The event aer_event is only used when CONFIG_PCIEAER is configured. It should not be created when it is not. When an event is created it creates around 5K of text and meta data regardless if the tracepoint is used or not. Instead of wasting this memory, put #ifdef around the event to not create it when it is not used.
