Subject: Re: [PATCH net-next] inet: add bound ports statistic

Hi Stephen,

I love your patch! Yet something to improve:

[auto build test ERROR on net-next/master]

url:    https://github.com/0day-ci/linux/commits/Stephen-Hemminger/inet-add-bound-ports-statistic/20180503-182729
config: i386-randconfig-x000-201817 (attached as .config)
compiler: gcc-7 (Debian 7.3.0-16) 7.3.0
reproduce:
        # save the attached .config to linux build tree
        make ARCH=i386 

All errors (new ones prefixed by >>):
