The analysis checks out on 7.1.y: 57918341dd19 ("bpf: Add sleepable
support for classic tracepoint programs") is not there, so the added
hlist_empty() early return runs before bpf_prog_array_valid() is ever
consulted and a BPF-only consumer stops firing.
Since this reverts a commit that already shipped in 7.1.6, I would like
your test result before queueing it - you mentioned you would have one
today. Ping the thread once you do and I will pick it up.
