A problem I ran into was that filtering for signals I was looking for vs all other signals getting sent around in the system required either logging everything to a file and parsing from there, or running a forked version of killsnoop to filter on the signal.\r\n\r\nThis PR includes a change to allow optional filtering of the signal that is passed to kill() to help reduce noise in cases like this.\r\n\r\nI haven't updated the examples as I'm not sure if this will be considered useful, but happy to do so if this gets the green light.ghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="Add killsnoop arg for filtering on signal" href="https://github.com/iovisor/bcc/pull/2929">PR #2929</a>: Add killsnoop arg for filte...#50012058157460664bcc-pr #500500false5004008SUCCESS1590448225843https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/500/git500https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc25/500/500https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc26/500/500https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc27/500/500https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=fc28/500/500https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1604/500/500https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1710/500/500https://buildbot.iovisor.org/jenkins/user/a.s.protopopov/my-views/view/all/job/bcc-pr/label=ubuntu1804/500/
