According to [kernel source][uid_valid] there is only one invalid UID, it is `(uint)-1` which should be `UINT_MAX`. So instead of adding another variable, like I did, it possible to check if `targ_uid` is `UINT_MAX` (or `-1`), but I don't think we should be stingy on variables in this case.\r\n\r\n[uid_valid]: https://github.com/torvalds/linux/blob/master/include/linux/uidgid.h#L113ghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="libbpf-tools: CO-RE opensnoop minor improvements" href="https://github.com/iovisor/bcc/pull/2811">PR #2811</a>: libbpf-tools: CO-RE opensno...#42114336297460664bcc-pr #421421false4213383SUCCESS1585460421235https://buildbot.iovisor.org/jenkins/user/yhs/my-views/view/all/job/bcc-pr/421/git421https://buildbot.iovisor.org/jenkins/user/yhs/my-views/view/all/job/bcc-pr/label=fc25/421/421https://buildbot.iovisor.org/jenkins/user/yhs/my-views/view/all/job/bcc-pr/label=fc26/421/421https://buildbot.iovisor.org/jenkins/user/yhs/my-views/view/all/job/bcc-pr/label=fc27/421/421https://buildbot.iovisor.org/jenkins/user/yhs/my-views/view/all/job/bcc-pr/label=fc28/421/421https://buildbot.iovisor.org/jenkins/user/yhs/my-views/view/all/job/bcc-pr/label=ubuntu1604/421/421https://buildbot.iovisor.org/jenkins/user/yhs/my-views/view/all/job/bcc-pr/label=ubuntu1710/421/421https://buildbot.iovisor.org/jenkins/user/yhs/my-views/view/all/job/bcc-pr/label=ubuntu1804/421/
