It's causing\r\nthe `bpf_has_kernel_btf` function to return True in systems without support\r\nfor BTF, making tools like opensnoop, klockstat and any other using kfuncs\r\nunusable in those systems.\r\n\r\nThe following Python script reproduces the problem:\r\n\r\n```\r\nfrom bcc import BPF\r\nprint(BPF.support_kfunc())\r\n```\r\n\r\nSigned-off-by: Mauricio Vásquez <mauricio@kinvolk.io>ghprbCommentBodynullghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="libbcc-py: Fix libbpf types" href="https://github.com/iovisor/bcc/pull/2923">PR #2923</a>: libbcc-py: Fix libbpf types#49015108207460664bcc-pr #490490false4903914SUCCESS1590087870804https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/490/git490https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc25/490/490https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc26/490/490https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc27/490/490https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc28/490/490https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1604/490/490https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1710/490/490https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1804/490/
