In preparation to enabling -Wimplicit-fallthrough, this patch silences the following warning: kernel/bpf/verifier.c: In function ‘check_return_code’: kernel/bpf/verifier.c:6106:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (env->prog->expected_attach_type == BPF_CGROUP_UDP4_RECVMSG || ^ kernel/bpf/verifier.c:6109:2: note: here case BPF_PROG_TYPE_CGROUP_SKB: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that is much clearer to explicitly add breaks in each case statement (that actually contains some code), rather than letting the code to fall through. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by:
