Subject: [PATCH 3/7] netconsole: do not release spin_lock before calling __netpoll_cleanup
Date: Fri, 27 Jul 2012 23:38:00 +0800 [thread overview]
Message-ID: <1343403484-29347-4-git-send-email-amwang@redhat.com> (raw)
In-Reply-To: <1343403484-29347-1-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.
