Subject: [PATCH] macvtap: remove wrong sock_put() in macvtap_put_queue()
Date: Mon, 13 Jun 2011 11:15:19 +0800	[thread overview]
Message-ID: <1307934919-4189-1-git-send-email-jasowang@redhat.com> (raw)

The calling of sock_put() should be delayed after synchronize_rcu(),
otherwise inconsist data may be seen during packets transmitting.
