Sorry for the long delay in replying, I update the kernels we use for
CI only infrequently. Here is an example of the build failure I'm
seeing, from kernel.org 5.10 LTS:

In file included from
/work/build/5.10.180/tools/testing/selftests/bpf/verifier/tests.h:59,
from test_verifier.c:355:
/work/build/5.10.180/tools/testing/selftests/bpf/verifier/ref_tracking.c:935:3:
error: 'struct bpf_test' has no member named 'fixup_map_ringbuf'; did
you mean 'fixup_map_in_map'?
935 | .fixup_map_ringbuf = { 11 },
| ^~~~~~~~~~~~~~~~~
| fixup_map_in_map

This is just doing make -C tools/testing/selftests/bpf after compiling a kernel.

Best
