Subject: [PATCH 1/2] block: fix return value on cfq_init() failure
Date: Mon, 4 Jun 2012 13:30:40 +0900	[thread overview]
Message-ID: <20120604043040.GA21357@google.com> (raw)
In-Reply-To: <20120601112954.GC3535@osiris.boeblingen.de.ibm.com>

cfq_init() would return zero after kmem cache creation failure.  Fix
so that it returns -ENOMEM.
