-      The equivalent of the WCE bit in the Caching Mode Page in
-      <xref target="SBC3" /> is the Write Cache Enable field in the
-      NVMe Get Features command, see Section 6.3.3.2 of
-      <xref target="NVME-STLR" />.  If a write cache is enable
-      on a NVMe device used as a storage device for the pNFS SCSI layout,
-      the MDS must ensure to use the NVMe FLUSH command to flush
-      the volatile write cache.
+      The Volatile Write Cache Enable (WCE) bit (i.e., bit 00) in
+      the Volatile Write Cache Feature (Feature Identifier 06h)
+      is the Write Cache Enable field in the NVMe Get Features command
+      (see Section 6.3.3.2 of <xref target="NVME-STLR" />).
