Hi Peter,
I love your patch! Yet something to improve:
[auto build test ERROR on tip/auto-latest]
[cannot apply to tip/locking/core tip/x86/asm linus/master tip/x86/core v5.7-rc7 next-20200528]
[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]
