Re: [ovs-dev] [PATCH ovn v2 13/13] tutorial: Add tutorial for OVN Interconnection.
Bleep bloop. Greetings Han Zhou, I am a robot and I have tried out your patch. Thanks for your contribution. I encountered some error that I wasn't expecting. See the details below. checkpatch: WARNING: Line is 85 characters long (recommended limit is 79) #122 FILE: Documentation/tutorials/ovn-interconnection.rst:77: --ovn-northd-nb-db= --ovn-northd-sb-db= [more options] start_ic Lines checked: 270, Warnings: 1, Errors: 0 Please check this out. If you feel there has been an error, please email acon...@redhat.com Thanks, 0-day Robot ___ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
