I don't understand the need for a per driver list of callbacks.
Your concern seems to be that drivers will get confused by multiple
subsystems trying to bind blocks. We have a feature flag for TC
offloads, why can't netfilter have one too? Way simpler.
If I may comment on the patches in general this series is really hard
to follow. Changes are split into patches in a strange way, and the
number of things called some combination of block cb and list makes my
head hurt :/
