The problem was introduced by commit f4b8c0710ab6 ("selftests/bpf: Add
verifier test for release_reference()") in your tree. Seems like
fixup_map_ringbuf was introduced in upstream commit 4237e9f4a962
("selftests/bpf: Add verifier test for PTR_TO_MEM spill") but that
wasn't backported.

To restate my original question: how can we avoid breaking BPF
selftests? From personal experience this happens somewhat regularly.

Best
Lorenz
