Subject: [PATCH net-next 6/7] ipv6: addrconf: do not block BH in /proc/net/if_inet6 handling
Date: Mon, 23 Oct 2017 16:17:50 -0700	[thread overview]
Message-ID: <20171023231751.29530-7-edumazet@google.com> (raw)
In-Reply-To: <20171023231751.29530-1-edumazet@google.com>

Table is really RCU protected, no need to block BH
