[-Werror=implicit-function-declaration] Dropped from the 6.12 queue along with its two dep-of companions: - libbpf: Stringify errno in log messages in libbpf.c - libbpf: Prevent double close and leak of btf objects - libbpf: Change log level of btf loading error message The errstr() helper would need a larger libbpf refactor (c68b6fdc3600 and its prerequisites) to come along, which doesn't apply cleanly. Thanks for the report. -- Thanks, Sasha
