I tried to reproduce this, without success. And it's not really clear to me
how it could be related to the change either...

Hi Andres,
Sorry for the inconvenience, this error can be reproduced by `make
O=/tmp/kselftest -C tools/testing/selftests/bpf`, but it shouldn't be
related to your commit, the build of parent commit stopped in early
stage which caused the false positive.
Best Regards,
Rong Chen
