Why? Because that change attempts to prefix `/proc/PID/root` to everything, and if the process is in a container w/ a different pid namespace than root, `/proc/42/root/proc/42/exe` is unlikely to mean anything and almost certainly won't mean the same thing as `/proc/42/exe`.\r\n\r\nLet's not prefix `/proc/PID/root` to procfs paths. Then the above case will be unbroken.\r\nghprbCommentBody[buildbot, ok to test]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="Don't prepend /proc/PID/root to user-supplied USDT binary paths starting with /proc already" href="https://github.com/iovisor/bcc/pull/2495">PR #2495</a>: Don't prepend /proc/PID/roo...#5114924927460664bcc-pr #5151false51429SUCCESS1565904344212https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/51/git51https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc25/51/51https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc26/51/51https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc27/51/51https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc28/51/51https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=ubuntu1604/51/51https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=ubuntu1710/51/51https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=ubuntu1804/51/
