Davide Caratti a90f6dcefc net/sched: don't use dynamic lockdep keys with clsact/ingress/noqueue ... Currently we are registering one dynamic lockdep key for each allocated qdisc, to avoid false deadlock reports when mirred (or TC eBPF) redirects packets to another device while the root lock is acquired [1]. Since dynamic keys are a limited resource, we can save them at least for qdiscs that are not meant to acquire the root lock in the traffic path, or to carry traffic at all, like: - clsact - ingress - noqueue Don't register dynamic keys for the above schedulers, so that we hit MAX_LOCKDEP_KEYS later in our tests.
