I'm getting following errors when compiling with -Wcast-qual: bpf/btf.h: In function ‘btf_var* btf_var(const btf_type*)’: bpf/btf.h:296:33: warning: cast from type ‘const btf_type*’ to type ‘btf_var*’ casts away qualifiers [-Wcast-qual] 296 | return (struct btf_var *)(t + 1); | ^ The argument is const so the cast to following struct btf_var pointer should be const as well.
