Subject: [for-next][PATCH 09/20] tracing: Make tracing_selftest_running global to the tracing subsystem
Date: Sun, 08 Feb 2026 21:20:35 -0500 [thread overview]
Message-ID: <20260209022053.530777281@kernel.org> (raw)
In-Reply-To: 20260209022026.627895421@kernel.org
From: Steven Rostedt <rostedt@goodmis.org>
The file trace.c has become a catchall for most things tracing. Start
making it smaller by breaking out various aspects into their own files.
Make the variable tracing_selftest_running global so that it can be used
by other files in the tracing subsystem and trace.c can be split up.
