From 11d39cfeecfc9d92a5faa2a55c228e796478e0cb Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Mon, 8 Mar 2021 20:43:22 -0800 Subject: selftests/bpf: Fix compiler warning in BPF_KPROBE definition in loop6.c Add missing return type to BPF_KPROBE definition. Without it, compiler generates the following warning: progs/loop6.c:68:12: warning: type specifier missing, defaults to 'int' [-Wimplicit-int] BPF_KPROBE(trace_virtqueue_add_sgs, void *unused, struct scatterlist **sgs, ^ 1 warning generated.
