Dropped 271abf041cb3 ("libbpf: Stringify errno in log messages in
libbpf.c") from the 6.12 queue, along with its two dep-of companions
(libbpf: Prevent double close and leak of btf objects; libbpf: Change
log level of btf loading error message), since c68b6fdc3600 doesn't
apply without a larger libbpf refactor coming along.

Thanks for the report.
