Hi Paolo, I love your patch! Yet something to improve: [auto build test ERROR on kvm/linux-next] [also build test ERROR on linus/master v5.6-rc4 next-20200305] [cannot apply to linux/master vhost/linux-next] [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] url:
