parentnet: sched: track rtnl lock status when validating extensions (diff)
net: sched: extend proto ops with 'put' callback
Add optional tp->ops->put() API to be implemented for filter reference counting. This new function is called by cls API to release filter reference for filters returned by tp->ops->change() or tp->ops->get() functions. Implement tfilter_put() helper to call tp->ops->put() only for classifiers that implement it.
