Subject: [PATCH AUTOSEL 5.3 36/71] libnvdimm/region: Initialize bad block for volatile namespaces
Date: Tue, 1 Oct 2019 12:38:46 -0400 [thread overview]
Message-ID: <20191001163922.14735-36-sashal@kernel.org> (raw)
In-Reply-To: <20191001163922.14735-1-sashal@kernel.org>
From: "Aneesh Kumar K.V" <aneesh.kumar@linux.ibm.com>
[ Upstream commit c42adf87e4e7ed77f6ffe288dc90f980d07d68df ]
We do check for a bad block during namespace init and that use
region bad block list. We need to initialize the bad block
for volatile regions for this to work. We also observe a lockdep
warning as below because the lock is not initialized correctly
since we skip bad block init for volatile regions.
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.
