Subject: Re: [PATCH v2 5/5] net: Add Open vSwitch kernel components.

There are lots of new global symbols created by this module.
Since C has no namespaces, a kernel module needs to in general
stick to one prefix and naming convention.

$ nm openvswitch.ko | grep -v ' U ' | grep -v ' [btrd] '

I recommend that all non-static functions an data be prefixed with one
string (like ovs_).
