Subject: linux-next: build warning after merge of the ftrace tree

Hi all,

After merging the ftrace tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

In file included from kernel/trace/trace.c:52:
kernel/trace/trace.h:804:13: warning: 'latency_fsnotify' defined but not used [-Wunused-function]
  804 | static void latency_fsnotify(struct trace_array *tr) { }
      |             ^~~~~~~~~~~~~~~~

Introduced by commit

  91edde2e6ae1 ("ftrace: Implement fs notification for tracing_max_latency")

"inline" missing :-(

Cheers,
Stephen Rothwell
