It's better than fiddling with the counts in userspace b/c if\r\nthe userspace program crashes then the semaphore count does not get\r\ndecremented.\r\n\r\nIt's also better b/c the kernel can activate the semaphore for all\r\nprocesses that have the target mapped into memory. Currently with bcc,\r\nyou have to provide the pid of each process you want to activate a\r\nsemaphore for and then bcc will go poke /proc/pid/mem at the right\r\noffset.ghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="uprobe: Add ref_cnt_offset arg to bpf_attach_uprobe" href="https://github.com/iovisor/bcc/pull/3135">PR #3135</a>: uprobe: Add ref_cnt_offset ...#72912687977460664bcc-pr #729729false7295840SUCCESS1603407216667https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/729/git729https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc25/729/729https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc26/729/729https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc27/729/729https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc28/729/729https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=ubuntu1604/729/729https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=ubuntu1710/729/729https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=ubuntu1804/729/
