From 583c53185399cea5c51195064564d1c9ddc70cf3 Mon Sep 17 00:00:00 2001 From: Mathieu Malaterre Date: Wed, 16 Jan 2019 20:29:40 +0100 Subject: bpf: Make function btf_name_offset_valid static Initially in commit 69b693f0aefa ("bpf: btf: Introduce BPF Type Format (BTF)") the function 'btf_name_offset_valid' was introduced as static function it was later on changed to a non-static one, and then finally in commit 23127b33ec80 ("bpf: Create a new btf_name_by_offset() for non type name use case") the function prototype was removed. Revert back to original implementation and make the function static. Remove warning triggered with W=1: kernel/bpf/btf.c:470:6: warning: no previous prototype for 'btf_name_offset_valid' [-Wmissing-prototypes] Fixes: 23127b33ec80 ("bpf: Create a new btf_name_by_offset() for non type name use case") Signed-off-by: Mathieu Malaterre Acked-by: Martin KaFai Lau Signed-off-by: Daniel Borkmann --- kernel/bpf/btf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'kernel') diff --git a/kernel/bpf/btf.c b/kernel/bpf/btf.c index a2f53642592b..befe570be5ba 100644 --- a/kernel/bpf/btf.c +++ b/kernel/bpf/btf.c @@ -467,7 +467,7 @@ static const struct btf_kind_operations *btf_type_ops(const struct btf_type *t) return kind_ops[BTF_INFO_KIND(t->info)]; } -bool btf_name_offset_valid(const struct btf *btf, u32 offset) +static bool btf_name_offset_valid(const struct btf *btf, u32 offset) { return BTF_STR_OFFSET_VALID(offset) && offset < btf->hdr.str_len; -- cgit v1.2.3
