Hi,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on tip/sched/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]
