Subject: Re: [PATCH bpf-next] bpf: add bpf_ct_lookup_{tcp,udp}() helpers

Hi Matthew,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on bpf-next/master]
[also build test ERROR on next-20200117]
[cannot apply to bpf/master net-next/master net/master linus/master sparc-next/master v5.5-rc6]
[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]
