Subject: [patch -next] rtnetlink: unlock on error path in netlink_dump()
Date: Wed, 15 Jun 2011 16:11:42 +0300	[thread overview]
Message-ID: <20110615131142.GE23739@shale.localdomain> (raw)

In c7ac8679bec939 "rtnetlink: Compute and store minimum ifinfo dump
size", we moved the allocation under the lock so we need to unlock
on error path.
