Subject: [PATCH 012 of 13] md: Make 'reshape' a possible sync_action action.
Date: Fri, 17 Mar 2006 15:48:25 +1100 [thread overview]
Message-ID: <1060317044825.16232@suse.de> (raw)
In-Reply-To: 20060317154017.15880.patches@notabene
This allows reshape to be triggerred via sysfs (which is the
only way to start it happening).
