Subject: [PATCH 8/8] md/raid5: break stripe-batches when the array has failed.
Date: Fri, 22 May 2015 15:30:58 +1000 [thread overview]
Message-ID: <20150522053058.2117.38642.stgit@notabene.brown> (raw)
In-Reply-To: <20150522052802.2117.40527.stgit@notabene.brown>
Once the array has too much failure, we need to break
stripe-batches up so they can all be dealt with.
