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 5.10 LTS:

In file included from
from test_verifier.c:355:
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.
