Subject: [md PATCH 6/8] md/raid5: set reshape_position correctly when reshape starts.
Date: Mon, 03 Aug 2009 07:58:18 +1000 [thread overview]
Message-ID: <20090802215818.4198.79858.stgit@notabene.brown> (raw)
In-Reply-To: <20090802215444.4198.83094.stgit@notabene.brown>
As the internal reshape_progress counter is the main driver
for reshape, the fact that reshape_position sometimes starts with the
wrong value has minimal effect. It is visible in sysfs and that
is all.
