However, my goal is to\r\nuse this feature in Kubernetes: I am preparing to use this in Inspektor\r\nGadget to select specific Kubernetes pods, depending on a Kubernetes\r\nlabel selector. Kubernetes pods matching the label selector can come and\r\ngo during the execution of the bcc tools; Inspektor Gadget is updating\r\nthe BPF hash map used by the bcc tools accordingly.\r\n\r\n/cc @pothos (this PR needs https://github.com/iovisor/bcc/pull/2378)\r\nghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="tools: cgroup filtering in execsnoop/opensnoop" href="https://github.com/iovisor/bcc/pull/2651">PR #2651</a>: tools: cgroup filtering in ...#18013677797460664bcc-pr #180180false1801469SUCCESS1576680318964https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/180/git180https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=fc25/180/180https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=fc26/180/180https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=fc27/180/180https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=fc28/180/180https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=ubuntu1604/180/180https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=ubuntu1710/180/180https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=ubuntu1804/180/
