Message-ID: <1480645872-999847-1-git-send-email-ast@fb.com> Date: Thu, 1 Dec 2016 18:31:12 -0800 From: Alexei Starovoitov <ast@...com> To: "David S . Miller" <davem@...emloft.net> CC: Daniel Borkmann <daniel@...earbox.net>, <netdev@...r.kernel.org> Subject: [PATCH net-next] samples/bpf: silence compiler warnings silence some of the clang compiler warnings like: include/linux/fs.h:2693:9: warning: comparison of unsigned enum expression < 0 is always false arch/x86/include/asm/processor.h:491:30: warning: taking address of packed member 'sp0' of class or structure 'x86_hw_tss' may result in an unaligned pointer value include/linux/cgroup-defs.h:326:16: warning: field 'cgrp' with variable sized type 'struct cgroup' not at the end of a struct or class is a GNU extension since they add too much noise to samples/bpf/ build.
