Hi Jason,

I love your patch! Yet something to improve:

[auto build test ERROR on vhost/linux-next]
[also build test ERROR on linux/master linus/master v5.5-rc6 next-20200117]
[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]

base:   https://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git linux-next
config: i386-randconfig-g003-20200117 (attached as .config)

reproduce:
        # save the attached .config to linux build tree
        make ARCH=i386
