It rather uses bpf_map_lookup_and_delete_batch without using the return values. I did not succeed in writing bpf_map_delete_batch with only one BPF syscall with BPF_MAP_DELETE_BATCH. I doubt this is possible.\r\n\r\nbpf_map_delete_batch could be used to improve the table.clear() (less system calls) but it would only works for kernel v5.6 and later. How do you you manage this ? Do you let the kernel dependencies management in libbpf ?ghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="add bpf_map_lookup_batch and bpf_map_delete_batch in bcc" href="https://github.com/iovisor/bcc/pull/3363">PR #3363</a>: add bpf_map_lookup_batch an...#93613415367460664bcc-pr #936936false9367476SUCCESS1619292874518https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/936/git936https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=fc25/936/936https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=fc26/936/936https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=fc27/936/936https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=fc28/936/936https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=ubuntu1604/936/936https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=ubuntu1710/936/936https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=ubuntu1804/936/
