[PATCH v1 14/18] perf bpf: Fix -Wdiscarded-qualifiers under C23
From: Shreenidhi Shedi
Date: Sat May 09 2026 - 14:07:19 EST
glibc >= 2.42 defaults to -std=gnu23, which promotes
-Wdiscarded-qualifiers to an error.
util/bpf-loader.c: In function 'config_bpf_program':
util/bpf-loader.c:588:27: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] 588 | char *s = strchr(main_str, ':');
