Subject: [PATCH v2] tracing: Move d_max_latency out of CONFIG_FSNOTIFY protection
Date: Mon, 9 Feb 2026 19:46:31 -0500 [thread overview]
Message-ID: <20260209194631.788bfc85@fedora> (raw)
From: Steven Rostedt <rostedt@goodmis.org>
The tracing_max_latency shouldn't be limited if CONFIG_FSNOTIFY is defined
or not and it was moved out of that protection to be always available with
CONFIG_TRACER_MAX_TRACE. All was moved out except the dentry descriptor
for it (d_max_latency) and it failed to build on some configs.
Move that out of the CONFIG_FSNOTIFY protection too.
Fixes: ba73713da50e ("tracing: Clean up use of trace_create_maxlat_file()")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202602092133.fTdojd95-lkp@intel.com/
