fixed in attacehd version
*** Bug 2028126 has been marked as a duplicate of this bug. ***
Hi, is the target release version fixed?
PR merged 3 days ago, so I expect it'll make 4.9.12, though that would need some verification when it's actually released
verified! Created pods and checked netns on a node while pods were running and after pods were deleted. $ oc get clusterversion NAME VERSION AVAILABLE PROGRESSING SINCE STATUS version 4.9.12 True False 41m Cluster version is 4.9.12
