Sometimes tests are Ok and sometimes they fails. See the output of tests.\r\n``` \r\npython git:(add_subset_for_batch_ops) ✗ sudo python3 ./test_map_batch_ops.py\r\n...F....\r\n======================================================================\r\nFAIL: test_lookup_and_delete_batch_subset (__main__.TestMapBatch)\r\n----------------------------------------------------------------------\r\nTraceback (most recent call last):\r\n File \"./test_map_batch_ops.py\", line 94, in test_lookup_and_delete_batch_subset\r\n self.assertEqual(count, self.SUBSET_SIZE)\r\nAssertionError: 31 != 32\r\n\r\n----------------------------------------------------------------------\r\nRan 8 tests in 2.635s\r\n\r\nFAILED (failures=1)\r\n➜ python git:(add_subset_for_batch_ops) ✗ sudo python3 ./test_map_batch_ops.py\r\n........\r\n----------------------------------------------------------------------\r\nRan 8 tests in 2.613s\r\n\r\nOK\r\n```\r\nDo I need to call the lib.bpf_lookup_and_delete_batch() several times until the sum of the nb of elements returned matches the subset size ? For example, If my subset size is 32 and get only 31 elem on the first call, do I need to call it again for the last element ? :thinking: \r\n\r\nghprbCommentBody[buildbot, test this please]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="[WIP] finish to add support of subset in items_*_batch()" href="https://github.com/iovisor/bcc/pull/3440">PR #3440</a>: [WIP] finish to add support...#99212526237460664bcc-pr #992992false9927945SUCCESS1621644293104https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/992/git992https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=fc25/992/992https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=fc26/992/992https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=fc27/992/992https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=fc28/992/992https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=ubuntu1604/992/992https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=ubuntu1710/992/992https://buildbot.iovisor.org/jenkins/view/all/job/bcc-pr/label=ubuntu1804/992/
