+===========================
+
+NAME
+----
+ndctl-disable-passphrase - disabling passphrase for an NVDIMM
+
+SYNOPSIS
+--------
+[verse]
+'ndctl disable-passphrase' <dimm> [<options>]
+
+DESCRIPTION
+-----------
+Provide a generic interface for disabling passphrase for NVDIMM.
+Ndctl will search the user key ring for the associated DIMM. If no key is
+found, it will attempt to load the key blob from the expected location. Ndctl
+will remove the key and the key blob once passphrase is disabled.
