Which means the `/lib/modules/$(uname -r)/build` symlink still remains valid, but there's no `kconfig.h` there anymore[1]. This prevents bcc from using the `kheaders` (`/sys/kernel/kheaders.tar.xz`) fallback, instead making it fail later on:\r\n\r\n <built-in>:1:10: fatal error: './include/linux/kconfig.h' file not found\r\n #include \"./include/linux/kconfig.h\"\r\n ^~~~~~~~~~~~~~~~~~~~~~~~~~~\r\n 1 error generated.\r\n\r\n[1] https://bugs.gentoo.org/809347ghprbCommentBodynullghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="Check for kconfig.h presence, not just build dir" href="https://github.com/iovisor/bcc/pull/3588">PR #3588</a>: Check for kconfig.h presenc...#114813241827460664bcc-pr #11481148false11489193SUCCESS1631546203448https://buildbot.iovisor.org/jenkins/user/sumanthk/my-views/view/all/job/bcc-pr/1148/git1148https://buildbot.iovisor.org/jenkins/user/sumanthk/my-views/view/all/job/bcc-pr/label=fc25/1148/1148https://buildbot.iovisor.org/jenkins/user/sumanthk/my-views/view/all/job/bcc-pr/label=fc26/1148/1148https://buildbot.iovisor.org/jenkins/user/sumanthk/my-views/view/all/job/bcc-pr/label=fc27/1148/1148https://buildbot.iovisor.org/jenkins/user/sumanthk/my-views/view/all/job/bcc-pr/label=fc28/1148/1148https://buildbot.iovisor.org/jenkins/user/sumanthk/my-views/view/all/job/bcc-pr/label=ubuntu1604/1148/1148https://buildbot.iovisor.org/jenkins/user/sumanthk/my-views/view/all/job/bcc-pr/label=ubuntu1710/1148/1148https://buildbot.iovisor.org/jenkins/user/sumanthk/my-views/view/all/job/bcc-pr/label=ubuntu1804/1148/
