Hi Masami,

I love your patch! Perhaps something to improve:

[auto build test WARNING on next-20200115]
[cannot apply to tip/perf/core ia64/next tip/x86/core linus/master v5.5-rc6 v5.5-rc5 v5.5-rc4 v5.5]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

url:    https://github.com/0day-ci/linux/commits/Masami-Hiramatsu/tracing-kprobes-Introduce-async-unregistration/20200117-191143
base:    5b483a1a0ea1ab19a5734051c9692c2cfabe1327
reproduce:
        # apt-get install sparse
        # sparse version: v0.6.1-153-g47b6dfef-dirty
        make ARCH=x86_64 allmodconfig
        make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'

If you fix the issue, kindly add following tag
Reported-by: kbuild test robot <lkp@intel.com>


sparse warnings: (new ones prefixed by >>)

>> kernel/trace/trace_kprobe.c:331:10: sparse: sparse: symbol 'trace_kprobe_disabled_finished' was not declared. Should it be static?

Please review and possibly fold the followup patch.
