I really like this series, but your latest netdevsim RFC made me worry.

It is important to make sure that these devlink_put() and devlink_get()
calls will be out-of-reach from the drivers. Only core code should use
them.

get/put symbols are not exported so I think we should be safe
from driver misuse at this point. If we ever export them we 
should add a 

  WARN_ON(!(devlink->lock_flags & DEVLINK_LOCK_USE_REF));

Can you please add it as a comment above these functions?

Will do if the RFC sinks.

At least for now, till we discuss your RFC.
