Subject: [PATCH 03/14] netconsole: do not release spin_lock when calling __netpoll_cleanup
Date: Thu, 9 Aug 2012 23:00:15 +0800 [thread overview]
Message-ID: <1344524426-11588-4-git-send-email-amwang@redhat.com> (raw)
In-Reply-To: <1344524426-11588-1-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.
