Hi Masami,
I love your patch! Yet something to improve:
[auto build test ERROR on trace/for-next]
[also build test ERROR on lwn/docs-next linus/master v5.5-rc3]
[cannot apply to tip/perf/core next-20191220]
[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]

reproduce:
