Hi Marek,

I love your patch! Yet something to improve:

[auto build test ERROR on net/master]
[also build test ERROR on net-next/master linus/master v5.6-rc7 next-20200327]
[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]
