Actually, only this [issue](https://github.com/iovisor/bpftrace/issues/1833) mentioned this.\r\n\r\nI think it's helpful to add this to BCC.ghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="Add FENTRY_PROBE/FEXIT_PROBE" href="https://github.com/iovisor/bcc/pull/3618">PR #3618</a>: Add FENTRY_PROBE/FEXIT_PROBE#115012911847460664bcc-pr #11501150false11509209SUCCESS1631673780332https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/1150/git1150https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc25/1150/1150https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc26/1150/1150https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc27/1150/1150https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc28/1150/1150https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1604/1150/1150https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1710/1150/1150https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1804/1150/
