I love your patch! Yet something to improve:
[auto build test ERROR on arm64/for-next/core]
[also build test ERROR on powerpc/next tip/x86/mm linus/master v5.7-rc1 next-20200413]
[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]
