| [IPV6]: /proc/net/anycast6 unbalanced inet6_dev refcnt |
| |
| From: David Stevens <dlstevens@us.ibm.com> |
| |
| Reading /proc/net/anycast6 when there is no anycast address |
| on an interface results in an ever-increasing inet6_dev reference |
| count, as well as a reference to the netdevice you can't get rid of. |
