Subject: [PATCH 3/8] netconsole: do not release spin_lock when calling __netpoll_cleanup
Date: Mon,  6 Aug 2012 22:23:27 +0800	[thread overview]
Message-ID: <1344263012-4031-4-git-send-email-amwang@redhat.com> (raw)
In-Reply-To: <1344263012-4031-1-git-send-email-amwang@redhat.com>

With the previous patch applied, __netpoll_cleanup() is non-block now,
so we don't need to release the spin_lock before calling it.
