Hi Namhyung,

I love your patch! Perhaps something to improve:

[auto build test WARNING on tip/auto-latest]
[also build test WARNING on linux/master linus/master v5.5-rc3 next-20191219]
[cannot apply to tip/perf/core]
[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]
