A funny note is that we can't say just \"(void) f()\" to\r\nsuppress the warning, so I wrote it as \"(void) !!f()\", which works.\r\n\r\nSigned-off-by: Anton Protopopov <a.s.protopopov@gmail.com>ghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="libbpf-tools: syscall_helpers: fix a warning" href="https://github.com/iovisor/bcc/pull/3169">PR #3169</a>: libbpf-tools: syscall_helpe...#75212321357460664bcc-pr #752752false7526025SUCCESS1605417440481https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/752/git752https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc25/752/752https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc26/752/752https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc27/752/752https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc28/752/752https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=ubuntu1604/752/752https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=ubuntu1710/752/752https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=ubuntu1804/752/
