Miller" <davem@...emloft.net> Subject: [PATCH 4.1 17/95] ipv6: clean up dev_snmp6 proc entry when we fail to initialize inet6_dev 4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Sabrina Dubroca <sd@...asysnail.net> [ Upstream commit 2a189f9e57650e9f310ddf4aad75d66c1233a064 ] In ipv6_add_dev, when addrconf_sysctl_register fails, we do not clean up the dev_snmp6 entry that we have already registered for this device. Call snmp6_unregister_dev in this case.
