Since it's\r\nalways the first map we can reuse existing code and get rid of\r\nexe-specific helpers.\r\n\r\nWhile writing this I noticed that the remaining place `get_pid_exe` is used, the USDT code, potentially also has a bug due to `get_pid_exe` and shouldn't be using it either if so. Will follow up\r\n\r\nI still need to validate this. Plan on doing so with `libbpf-tools`' offcputime and hopefully some example that can be committed ghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="ProcSyms should treat the executable like any other mapped file when symbolizing" href="https://github.com/iovisor/bcc/pull/3498">PR #3498</a>: ProcSyms should treat the e...#104212445867460664bcc-pr #10421042false10428345SUCCESS1624121287296https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/1042/git1042https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=fc25/1042/1042https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=fc26/1042/1042https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=fc27/1042/1042https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=fc28/1042/1042https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=ubuntu1604/1042/1042https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=ubuntu1710/1042/1042https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=ubuntu1804/1042/
