Subject: Re: [PATCH net-next 1/8] net: ipv4: refactor
__ip_route_output_key_hash
Hi David,
[auto build test ERROR on net-next/master]
url: https://github.com/0day-ci/linux/commits/Roopa-Prabhu/net-extend-RTM_GETROUTE-to-return-fib-result/20170525-053253
config: openrisc-or1ksim_defconfig (attached as .config)
compiler: or1k-linux-gcc (GCC) 5.4.0
reproduce:
wget https://raw.githubusercontent.com/01org/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=openrisc
Note: the linux-review/Roopa-Prabhu/net-extend-RTM_GETROUTE-to-return-fib-result/20170525-053253 HEAD 083c4ee9e124d0acf29d159ced8a22cb41665a7a builds fine.
It only hurts bisectibility.
