This is not useful when people wants to\r\nknow why process terminates, not thread.\r\n\r\nWhen `--main-thread` option is specified, exitsnoop trace only\r\nmain thread termination by checking both PID and TID. Because\r\nLinux ensures that PID equals to main thread TID\r\n\r\nI suppose `exitsnoop` should check both PID and TID as default behavior because its documentations says **Trace all process termination** but current implementation **traces all thread termination**. However I'm not sure that there is no problem to change default behavior for backward compatibility.ghprbCommentBody[buildbot, ok to test]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="tool: add option --main-thread for exitsnoop" href="https://github.com/iovisor/bcc/pull/2927">PR #2927</a>: tool: add option --main-thr...#49727226367460664bcc-pr #497497false4973984SUCCESS1590163917738https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/497/git497https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc25/497/497https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc26/497/497https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc27/497/497https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc28/497/497https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1604/497/497https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1710/497/497https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1804/497/
