Subject: [IPV6]: /proc/net/anycast6 unbalanced inet6_dev refcnt
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=aa6e4a96e7589948fe770744f7bb4f0f743dddaa;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[IPV6]: /proc/net/anycast6 unbalanced inet6_dev refcnt

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.
