From dbdd9a52e38a4a93adfa4d0278801cce4fad98eb Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 10 Mar 2011 16:34:38 -0800 Subject: ipv4: Remove redundant RCU locking in ip_check_mc(). All callers are under rcu_read_lock() protection already. Rename to ip_check_mc_rcu() to make it even more clear. Signed-off-by: David S.
