Alan Maguire 70f9365a8f bpf: Eliminate remaining "make W=1" warnings in kernel/bpf/btf.o ... [ Upstream commit 2454075f8e2915cebbe52a1195631bc7efe2b7e1 ] As reported by Mirsad [1] we still see format warnings in kernel/bpf/btf.o at W=1 warning level: CC kernel/bpf/btf.o ./kernel/bpf/btf.c: In function ‘btf_type_seq_show_flags’: ./kernel/bpf/btf.c:7553:21: warning: assignment left-hand side might be a candidate for a format attribute [-Wsuggest-attribute=format] 7553 | sseq.showfn = btf_seq_show; | ^ ./kernel/bpf/btf.c: In function ‘btf_type_snprintf_show’: ./kernel/bpf/btf.c:7604:31: warning: assignment left-hand side might be a candidate for a format attribute [-Wsuggest-attribute=format] 7604 | ssnprintf.show.showfn = btf_snprintf_show; | ^ Combined with CONFIG_WERROR=y these can halt the build. The fix (annotating the structure field with __printf()) suggested by Mirsad resolves these. Apologies I missed this last time. No other W=1 warnings were observed in kernel/bpf after this fix.
