Hi, Thanks for the reminder. This change was not tested on real hardware. It was found by code inspection of the representor teardown path; I did not reproduce the UAF at runtime and no stack trace was observed. The fix is based on the RCU/NAPI lifetime analysis described in the commit message. If a future revision is needed for other reasons, I will make sure to include this information in the commit message. Thanks, Linkui
