The problem is bpf_spin_lock appears in kernel v5.1. So I have removed the call to `counts.clear()` since it is not mandatory. Instead I compute the delta during the interval.\r\nghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="dirtop.py : Fix a race condition made by counts.clear().
