From: Colin Ian King <colin.king@xxxxxxxxxxxxx> Function skip_callee is local to the source and does not need to be in global scope, so make it static. Also return NULL rather than 0. Cleans up two sparse warnings: symbol 'skip_callee' was not declared. Should it be static? Using plain integer as NULL pointer Signed-off-by: Colin Ian King <colin.king@xxxxxxxxxxxxx> --- kernel/bpf/verifier.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/kernel/bpf/verifier.c b/kernel/bpf/verifier.c index 2f6f09cd1925..52689f2abbcb 100644 --- a/kernel/bpf/verifier.c +++ b/kernel/bpf/verifier.c @@ -823,6 +823,7 @@ static int check_subprogs(struct bpf_verifier_env *env) return 0; } +static struct bpf_verifier_state *skip_callee(struct bpf_verifier_env *env, const struct bpf_verifier_state *state, struct bpf_verifier_state *parent, @@ -867,7 +868,7 @@ struct bpf_verifier_state *skip_callee(struct bpf_verifier_env *env, verbose(env, "verifier bug regno %d tmp %p\n", regno, tmp); verbose(env, "regno %d parent frame %d current frame %d\n", regno, parent->curframe, state->curframe); - return 0; + return NULL; } static int mark_reg_read(struct bpf_verifier_env *env, -- 2.14.1 -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
