I tried, as you suggested, to revert 2e81d08459c32c57d037ad160e755bcfe6d5003b (libbpf: Stringify errno in log messages in libbpf.c) 5c758117c381172ccb60fe9a0313705794ccdce2 (libbpf: Prevent double close and leak of btf objects) a8061c6ed62cc94a5e19f0e31d03d23ff65d638a (libbpf: Change log level of btf loading error message) but no matter how I do the revert, I get a conflict and I can't figure out how to resolve that. Will wait to retest an -rc2 once it's pushed out... Beste Grüße, Peter Schneider -- Climb the mountain not to plant your flag, but to embrace the challenge, enjoy the air and behold the view.
