Subject: [ndctl PATCH v5 5/7] ndctl/namespace: Minimize label data transfer for autolabel
Date: Mon, 05 Aug 2019 17:09:29 -0700	[thread overview]
Message-ID: <156505016983.848599.11002390849262331259.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <156505014382.848599.16271067825582995055.stgit@dwillia2-desk3.amr.corp.intel.com>

Use the new ndctl_dimm_read_label_index() helper to minimize the amount
of label I/O needed to execute an autolabel event.
