From 1ef26d8b2ca5d8715563c951083cf6c385c77d1f Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Google)" Date: Thu, 7 Sep 2023 22:19:11 -0400 Subject: [PATCH] tracing: Use the new eventfs descriptor for print trigger The check to create the print event "trigger" was using the obsolete "dir" value of the trace_event_file to determine if it should create the trigger or not. But that value will now be NULL because it uses the event file descriptor. Change it to test the "ef" field of the trace_event_file structure so that the trace_marker "trigger" file appears again.
