Subject: [PATCH] netdevice: Add missing parentheses in macro
Date: Wed, 14 Jan 2015 16:52:35 +0900 [thread overview]
Message-ID: <1421221955-9505-1-git-send-email-bpoirier@suse.de> (raw)
For example, one could conceivably call
for_each_netdev_in_bond_rcu(condition ? bond1 : bond2, slave)
and get an unexpected result.
