For example,\r\nSasha Goldshtein's linux-tracing-workshop\r\n https://github.com/goldshtn/linux-tracing-workshop\r\nis referenced in bcc/docs/tutorial_bcc_python_developer.md.\r\nIt has a tool called lockstat.py which traces pthread_mutex_init\r\nto collect some lock statistics for userspace locks.\r\n\r\nIn bcc, in the past, we also had an effort to gather userspace\r\nlock statistics with the same name lockstat.py.\r\n https://github.com/iovisor/bcc/pull/1268\r\n\r\nIn the future, bcc could have a lockstat tool tracing userspace\r\nlocks. So let us rename the current lockstat.py to klockstat.py\r\nto clearly express its scope.ghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="rename tool lockstat.py to klockstat.py" href="https://github.com/iovisor/bcc/pull/2634">PR #2634</a>: rename tool lockstat.py to ...#16014069367460664bcc-pr #160160false1601308SUCCESS1575523610460https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/160/git160https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=fc25/160/160https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=fc26/160/160https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=fc27/160/160https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=fc28/160/160https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=ubuntu1604/160/160https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=ubuntu1710/160/160https://buildbot.iovisor.org/jenkins/user/jmarchan/my-views/view/all/job/bcc-pr/label=ubuntu1804/160/
