Hi Dmitry,
I love your patch! Yet something to improve:
[auto build test ERROR on char-misc/char-misc-testing]
[cannot apply to v5.4-rc1 next-20191002]
[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

The way loadavg is tracked during nohz only pays attention to the load
upon entering nohz. This can be particularly noticeable if nohz is

system.
