Subject: [ndctl PATCH 7/8] ndctl/namespace: Always zero info-blocks
Date: Tue, 12 Feb 2019 13:29:24 -0800	[thread overview]
Message-ID: <155000696457.348282.2462787488474915269.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <155000692826.348282.2795434657787204298.stgit@dwillia2-desk3.amr.corp.intel.com>

Do not gate zeroing on whether a namespace is claimed by a personality.
The namespace might not have been able to be claimed due to info-block
corruption.
