Subject: [PATCH] trace: eradicate noisy warning in trace_osnoise.c
Date: Fri, 30 Jul 2021 17:00:55 -0700	[thread overview]
Message-ID: <20210731000055.28876-1-rdunlap@infradead.org> (raw)

OK, I'm officially tired of this noise warning coming from
trace_osnoise.c, so shut it up. Also, adding new warnings is not OK.

../kernel/trace/trace_osnoise.c: In function ‘start_kthread’:
../kernel/trace/trace_osnoise.c:1461:8: warning: ‘main’ is usually a function [-Wmain]
  void *main = osnoise_main;
        ^~~~

Fixes: c8895e271f79 ("trace/osnoise: Support hotplug operations")
