Subject: [PATCH 004 of 6] md: Clean out unplug and other queue function on md shutdown
Date: Tue, 20 Feb 2007 17:35:05 +1100 [thread overview]
Message-ID: <1070220063505.16178@suse.de> (raw)
In-Reply-To: 20070220172544.15678.patches@notabene
The mddev and queue might be used for another array which does not
set these, so they need to be cleared.
