Public bug reported:
On Ubuntu 25.04, after running FV tests for our application, sometimes
one of the nodes running tests stops responding to ssh. Examining the
serial console shows a lot of hung task warnings in
bpf_prog_free_deferred (see below). Perhaps it has deadlocked?
Our FV tests spin up and tear down lots of docker containers to simulate
kubernetes clusters, attaching BPF programs to hooks such as tc, tcx and
cgroup hooks within the containers and then letting them be reclaimed.
