Toke Høiland-Jørgensen b3051cd82d libbpf: Fix error handling in bpf_map__reuse_fd() ... [ Upstream commit d1b4574a4b ] bpf_map__reuse_fd() was calling close() in the error path before returning an error value based on errno. However, close can change errno, so that can lead to potentially misleading error messages. Instead, explicitly store errno in the err variable before each goto.
